Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies The unaudited condensed consolidated financial statements included herein have been prepared by Rexnord Corporation (“Rexnord” or the “Company”) in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, the condensed consolidated financial statements include all adjustments necessary for a fair presentation of the results of operations for the interim periods. Following the end of the Company's fiscal year ended March 31, 2020, the Company transitioned to a December 31 fiscal year-end date. Results for the interim periods are not necessarily indicative of results that may be expected for the year ending December 31, 2021. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company's Transition Report on Form 10-K for the nine-month transition period ended December 31, 2020 (the "Transition Period"). The Company Rexnord is a growth-oriented, multi-platform industrial company with what it believes to be leading market shares and highly-trusted brands that serve a diverse array of global end markets. The Company's heritage of innovation and specification have allowed it to provide highly-engineered, mission-critical solutions to customers for decades and affords it the privilege of having long-term, valued relationships with market leaders. The Company operates in a disciplined way and the Rexnord Business System (“RBS”) is its operating philosophy. Grounded in the spirit of continuous improvement, RBS creates a scalable, process-based framework that focuses on driving superior customer satisfaction and financial results by targeting world-class operating performance throughout all aspects of its business. The Process & Motion Control platform designs, manufactures, markets and services a comprehensive range of specified, highly-engineered mechanical components used within complex systems where the Company's customers' reliability requirements and costs of failure or downtime are high. The Process & Motion Control portfolio includes motion control products, shaft management products, aerospace components, and related value-added services.

The Water Management product portfolio includes professional grade water control and safety, water distribution and drainage, finish plumbing and site works products for primarily nonresidential buildings. Expected Spin-Off of Process & Motion Control Segment On February 15, 2021, Rexnord and Regal Beloit Corporation (“Regal”) entered into definitive agreements whereby Rexnord will separate its Process & Motion Control segment by way of a tax-free spin-off to Rexnord’s stockholders and then immediately combine it with Regal in a Reverse Morris Trust (“RMT”) transaction. Closing of this transaction is subject to various closing conditions, including the receipt of regulatory approvals, receipt of the approval of Regal and Rexnord stockholders (which each of Regal and Rexnord will solicit at special meetings of their respective stockholders at a later date), and other customary closing conditions. This transaction is expected to close in the fourth quarter of 2021. Recent Accounting Pronouncements In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate that is expected to be discontinued because of reference rate reform. The amendments in this update provide optional expedients and exceptions for applying GAAP to instruments affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in this ASU are effective for all entities as of March 12, 2020, In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ( "ASU 2019-12" )

Business Combinations [Abstract]
Acquisitions and Divestiture	Acquisitions and Divestiture Nine Month Transition Period Ended December 31, 2020 On December 11, 2020, the Company acquired substantially all of the assets of Hadrian Manufacturing Inc. and 100% of the stock of Hadrian Inc. (collectively, "Hadrian") for a total cash purchase price of $101.3 million, excluding transaction costs and net of cash acquired. During the three months ended March 31, 2021, the Company received a cash payment of $0.4 million from the sellers in connection with finalizing the acquisition date trade working capital, which is included in the total cash purchase price mentioned above. Hadrian, based in Burlington, Ontario, Canada, manufactures washroom partitions and lockers primarily used in institutional and commercial end markets and complements the Company's existing Water Management platform. The acquisition has been accounted for as a business combination and was recorded by allocating the preliminary purchase price to the fair value of assets acquired and liabilities assumed at the acquisition date. The excess of the purchase price over the fair value assigned to the assets acquired and liabilities assumed was recorded as goodwill. The preliminary purchase price allocations associated with the acquisition resulted in goodwill of $43.0 million ($37.0 million tax deductible), other intangible assets of $32.4 million (including tradenames of $0.8 million and $31.6 million of customer relationships), $17.1 million of fixed assets, $9.7 million of trade working capital and other net liabilities of $0.9 million. The preliminary purchase price allocations for Hadrian were adjusted during the three months ended March 31, 2021, resulting in a $0.2 million increase in goodwill related to aforementioned cash payment received, partially offset by the refinement of the estimated fair value of the liabilities assumed. The Company is continuing to evaluate the preliminary purchase price allocations for Hadrian related to the fair values assigned to fixed assets and net working capital acquired, which will be completed within the one year period following its acquisition date. On October 1, 2020, the Company completed the sale of its gearbox product line in China within its Process & Motion Control platform for aggregate cash consideration of $5.8 million. The gearbox product line was not material to the Company's consolidated statements of operations or financial position and did not meet the criteria to be presented as discontinued operations. In completing the sale, the Company sold inventory, fixed assets and other intellectual property associated with the business with a carrying value of $5.0 million. In addition, the Company allocated $1.8 million of goodwill from the Process & Motion Control platform that was included in the calculation of the gain on sale of the business. The Company recognized a gain of $0.8 million within other income (expense), net in the condensed consolidated statements of operations during the nine months ended December 31, 2020. On November 24, 2020, the Company acquired the remaining non-controlling interest in a Process & Motion Control joint venture for a cash purchase price of $0.3 million. The acquisition of the remaining minority interest was not material to the Company's condensed consolidated statements of operations or financial position. The Company's results of operations include the acquired operations subsequent to the acquisition date. Pro-forma results of operations and certain other U.S. GAAP disclosures related to the acquisition have not been presented because they are not significant to the Company's condensed consolidated statements of operations or financial position. Fiscal Year Ended March 31, 2020 On January 28, 2020, the Company acquired substantially all of the assets of Just Manufacturing Company ("Just Manufacturing") for a cash purchase price of $59.4 million, excluding transaction costs and net of cash acquired. Just Manufacturing, based in Franklin Park, Illinois, manufactures stainless steel sinks and plumbing fixtures primarily used in institutional and commercial end markets and complements the Company's existing Water Management platform. On May 10, 2019, the Company acquired substantially all of the assets of StainlessDrains.com, a manufacturer of stainless steel drains, grates and accessories for industrial and commercial end markets, for a cash purchase price of $24.8 million, excluding transaction costs and net of cash acquired. StainlessDrains.com, headquartered in Greenville, Texas, added complementary product lines to the Company's existing Water Management platform. The Company's results of operations include the acquired operations subsequent to the aforementioned acquisitions dates. Pro-forma results of operations and certain other U.S. GAAP disclosures related to these acquisitions have not been presented because they are not significant to the Company's condensed consolidated statements of operations or financial position. These acquisitions have been accounted for as business combinations and were recorded by allocating the purchase price to the fair value of assets acquired and liabilities assumed at the acquisition date. The excess of the purchase price over the fair value assigned to the assets acquired and liabilities assumed was recorded as goodwill. The purchase price allocations associated with these acquisitions resulted in tax deductible goodwill of $27.3 million, other intangible assets of $40.9 million (including tradenames of $2.2 million and $38.7 million of customer relationships), $8.4 million of fixed assets, $9.1 million of trade working capital and other net liabilities of $1.5 million. During the fiscal year ended March 31, 2020, the Company acquired the remaining non-controlling interest in a Process and Motion Control joint venture for a cash purchase price of $0.3 million. The acquisition of the remaining minority interest was not material to the Company's condensed consolidated statements of operations or financial position.

Restructuring and Related Activities [Abstract]
Restructuring and Other Similar Charges	Restructuring and Other Similar Charges During the three months ended March 31, 2021, the Company continued to execute various restructuring actions. These initiatives were implemented to drive efficiencies and reduce operating costs while also modifying the Company's footprint to reflect changes in the markets it serves, the impact of acquisitions on the Company's overall manufacturing capacity and the refinement of its overall product portfolio. These restructuring actions primarily resulted in workforce reductions, lease termination costs, and other facility rationalization costs. Management expects to continue executing initiatives and select product-line rationalizations to optimize its operating margin and manufacturing footprint. As the Company continues to evaluate the impact of the ongoing COVID-19 pandemic and the resulting effects on the global economy, the Company may also execute additional restructuring actions. As such, the Company expects further expenses related to workforce reductions, lease termination costs, and other facility rationalization costs. Since the Company’s evaluation of the impact of COVID-19 and other potential restructuring actions are in process, related restructuring expenses, if any, are not yet estimable. The following table summarizes the Company's restructuring and other similar charges during the three months ended March 31, 2021 and March 31, 2020, by classification of operating segment (in millions): Restructuring and Other Similar Charges Process & Motion Control Water Management Corporate Consolidated Employee termination benefits $ (0.1) $ 0.6 $ — $ 0.5 Contract termination and other associated costs 0.1 — — 0.1 Total restructuring and other similar costs $ — $ 0.6 $ — $ 0.6 Restructuring and Other Similar Charges Process & Motion Control Water Management Corporate Consolidated Employee termination benefits $ 5.3 $ 0.1 $ 0.1 $ 5.5 Contract termination and other associated costs 0.9 0.1 0.1 1.1 Total restructuring and other similar costs $ 6.2 $ 0.2 $ 0.2 $ 6.6 The following table summarizes the activity in the Company's restructuring accrual for the three months ended March 31, 2021 (in millions): Employee termination benefits Contract termination and other associated costs Total Restructuring accrual, December 31, 2020 (1) $ 6.1 $ 0.7 $ 6.8 Charges 0.5 0.1 0.6 Cash payments (2.7) (0.7) (3.4) Restructuring accrual, March 31, 2021 (1) $ 3.9 $ 0.1 $ 4.0 ____________________ (1) The restructuring accrual is included in other current liabilities in the condensed consolidated balance sheets. In connection with the ongoing supply chain optimization and footprint repositioning initiatives, the Company has taken several actions to consolidate existing manufacturing facilities and rationalize its product offerings. These actions require the Company to assess whether the carrying amount of impacted long-lived assets will be recoverable as well as whether the remaining useful lives require adjustment. As a result, the Company recognized accelerated depreciation of zero and

Revenue Recognition

Revenue Recognition	3 Months Ended
	Mar. 31, 2021
Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC 606, Revenue from Contracts with Customers ("ASC 606"). A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized when obligations under the terms of a contract with the customer are satisfied. For the majority of the Company's product sales, revenue is recognized at a point-in-time when control of the product is transferred to the customer, which generally occurs when the product is shipped from the Company's manufacturing facility to the customer. When contracts include multiple products to be delivered to the customer, generally each product is separately priced and is determined to be distinct within the context of the contract. Other than a standard assurance-type warranty that the product will conform to agreed-upon specifications, there are generally no other significant post-shipment obligations. The expected costs associated with standard warranties continues to be recognized as an expense when the products are sold. When the contract provides the customer the right to return eligible products or when the customer is part of a sales rebate program, the Company reduces revenue at the point of sale using current facts and historical experience by using an estimate for expected product returns and rebates associated with the transaction. The Company adjusts these estimates at the earlier of when the most likely amount of consideration that is expected to be received changes or when the consideration becomes fixed. Accordingly, an increase or decrease to revenue is recognized at that time. Sales and other taxes collected concurrent with revenue-producing activities are excluded from revenue. The Company has elected to recognize the cost for freight and shipping when control of products has transferred to the customer as a component of cost of sales in the condensed consolidated statements of operations. The Company classifies shipping and handling fees billed to customers as net sales and the corresponding costs are classified as Cost of sales in the condensed consolidated statements of operations. Revenue by Category The Company has two business segments, Process & Motion Control and Water Management. The following tables present our revenue disaggregated by customer type and originating geography (in millions): Three Months Ended March 31, 2021 March 31, 2020 Original equipment manufacturers/end users $ 180.3 $ 216.6 Maintenance, repair, and operations 140.6 147.0 Total Process & Motion Control $ 320.9 $ 363.6 Water safety, quality, flow control and conservation $ 189.8 $ 170.9 Water infrastructure 15.4 12.5 Total Water Management $ 205.2 $ 183.4 Three Months Ended Process & Motion Control Water Management United States and Canada $ 190.9 $ 203.8 Europe 79.6 — Rest of world 50.4 1.4 Total $ 320.9 $ 205.2 Three Months Ended Process & Motion Control Water Management United States and Canada $ 232.3 $ 179.4 Europe 82.3 — Rest of world 49.1 4.0 Total $ 363.6 $ 183.4 Contract Balances For substantially all of the Company's Process & Motion Control and Water Management product sales, the customer is billed 100% of the contract value when the product ships and payment is generally due 30 days from shipment. Certain contracts include longer payment periods; however, the Company has elected to utilize the practical expedient in which the Company will only recognize a financing component to the sale if payment is due more than one year from the date of shipment. The Company receives payment from customers based on the contractual billing schedule and specific performance requirements established in the contract. Billings are recorded as accounts receivable when an unconditional right to the contractual consideration exists. Contract assets arise when the Company performs by transferring goods or services to a customer before the customer pays consideration, or before the customer’s payment is due. A contract liability exists when the Company has received consideration or the amount is due from the customer in advance of revenue recognition. Contract liabilities and contract assets are recognized in Other current liabilities and Receivables, net, respectively, in the Company's condensed consolidated balance sheets. The following table presents changes in the Company’s contract assets and liabilities during the three months ended March 31, 2021 (in millions): Balance Sheet Classification December 31, 2020 Additions Deductions March 31, 2021 Contract assets Receivables, net $ 0.1 $ — $ (0.1) $ — Contract liabilities (1) Other current liabilities $ 4.0 $ 0.3 $ (0.9) $ 3.4 ____________________ (1) Contract liabilities are reduced when revenue is recognized. Backlog The Company has a backlog of $373.4 million as of March 31, 2021, which represents the most likely amount of consideration expected to be received in satisfying the remaining backlog under open contracts. The Company has elected to use the optional exemption provided by ASC 606-10-50-14A for variable consideration, and has not included estimated rebates in the amount of unsatisfied performance obligations. The Company expects to recognize approximately 88% of the unsatisfied performance obligations as revenue in the remaining nine months of the year ending December 31, 2021, and the remaining approximately 12% in 2022 and beyond. Timing of Performance Obligations Satisfied at a Point in Time The Company determined that the customer is able to control the product when it is delivered to them; thus, depending on the shipping terms, control will transfer at different points between the Company's manufacturing facility or warehouse and the customer’s location. The Company considers control to have transferred upon shipment or delivery because the Company has a present right to payment at that time, the customer has legal title to the asset, the Company has transferred physical possession of the asset, and the customer has significant risks and rewards of ownership of the asset. Variable Consideration The Company provides volume-based rebates and the right to return product to certain customers, which are accrued for based on current facts and historical experience. Rebates are paid either on an annual or quarterly basis. There are no other significant variable consideration elements included in the Company's contracts with customers. Contract Costs The Company has elected to expense contract costs as incurred if the amortization period is expected to be one year or less. If the amortization period of these costs is expected to be greater than one year, the costs would be subject to capitalization. As of March 31, 2021, the contract assets capitalized, as well as amortization recognized in the three months ended March 31, 2021, are not significant and there have been no impairment losses recognized.

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes for all periods presented is based on an estimated effective income tax rate for the respective fiscal years. The estimated annual effective income tax rate is determined excluding the effect of significant discrete items or items that are reported net of their related tax effects. The tax effect of significant discrete items is reflected in the period in which they occur. The Company's income tax expense is impacted by a number of factors, including the amount of taxable earnings derived in foreign jurisdictions with tax rates that are generally higher than the U.S. federal statutory rate, state tax rates in the jurisdictions where the Company does business and the Company's ability to utilize various tax credits, capital loss and net operating loss (“NOL”) carryforwards. The Company regularly reviews its deferred tax assets for recoverability and valuation allowances are established based on historical losses, projected future taxable income and the expected timing of the reversals of existing temporary differences, as deemed appropriate. In addition, all other available positive and negative evidence is taken into consideration for purposes of determining the proper balances of such valuation allowances. As a result of this review, the Company continues to maintain a full valuation allowance against U.S. federal and state capital loss carryforwards and a partial valuation allowance against certain foreign NOL carryforwards and other related foreign deferred tax assets, as well as certain U.S. state NOL carryforwards. Future changes to the balances of these valuation allowances, as a result of this continued review and analysis by the Company, could result in a material impact to the financial statements for such period of change. The income tax provision was $17.2 million in the three months ended March 31, 2021, compared to $6.4 million in the three months ended March 31, 2020. The effective income tax rate for the three months ended March 31, 2021, was 25.6% versus 18.2% in the three months ended March 31, 2020. The effective income tax rate for the three months ended March 31, 2021 was above the U.S. federal statutory rate of 21% primarily due to the accrual of foreign income taxes, which are generally above the U.S. federal statutory rate, the accrual of unrecognized income tax benefits in which such realization is not deemed more-likely-than-not, the accrual of additional income taxes associated with compensation deduction limitations under Section 162(m) of the Internal Revenue Code and the accrual of various state income taxes, partially offset by the recognition of a discrete foreign financing-related income tax benefit, as well as the recognition of income tax benefits associated with foreign-derived intangible income (“FDII”). The effective income tax rate for the three months ended March 31, 2020 was below the U.S. federal statutory rate of 21% primarily due to the recognition of certain previously unrecognized tax benefits due to the lapse of the applicable statutes of limitations and the recognition of income tax benefits associated with FDII, partially offset by the accrual of foreign income taxes, which are generally above the U.S. federal statutory rate, the accrual of additional income taxes associated with global intangible low-taxed income (“GILTI”) and the accrual of various state income taxes. The Company’s total liability for net unrecognized tax benefits as of March 31, 2021 and December 31, 2020, was $18.5 million and $18.6 million, respectively. The Company recognizes accrued interest and penalties related to unrecognized income tax benefits in income tax expense. As of March 31, 2021 and December 31, 2020, the total amount of gross, unrecognized income tax benefits included $1.6 million of accrued interest and penalties. The Company recognized $0.2 million and $(0.5) million of net interest and penalties as income tax expense (benefit) during the three months ended March 31, 2021 and March 31, 2020, respectively. The Company conducts business in multiple locations within and outside the U.S. Consequently, the Company is subject to periodic income tax examinations by domestic and foreign income tax authorities. Currently, the Company is undergoing routine, periodic income tax examinations in both domestic and foreign jurisdictions. During the three months ended June 30, 2020, the Internal Revenue Service (the “IRS”) completed an income tax examination of the Company’s U.S. consolidated federal income tax returns for the tax years ended March 31, 2016 and 2017. The Company paid approximately $1.5 million upon the conclusion of such examination, all of which was previously accrued in the Company’s financial statements. During the three months ended March 31, 2020, the German tax authorities concluded an examination of the corporate income and trade tax returns for the Company’s CENTA German subsidiary for the tax years ended December 31, 2014 through December 31, 2017. The conclusion of the tax examination resulted in additional tax liabilities of approximately $1.7 million, all of which is subject to indemnification under the terms of the applicable purchase agreement or otherwise appropriately accrued in the Company’s financial statements. During the three months ended March 31, 2020, the Italian tax authorities began conducting an income tax examination of the income tax return of one of the Company’s Italian subsidiaries for the tax year ended March 31, 2018. In addition, certain of the Company’s German subsidiaries are currently undergoing a corporate income and trade tax examination by the German tax authorities for the tax years or period ended March 31, 2015 through March 31, 2018. In addition, in accordance with the terms of the VAG sale agreement, the Company is required to indemnify the purchaser for any future income tax liabilities associated with all open tax years ending prior to, and including, the short period ended on the date of the Company's sale of VAG. The VAG German entities are currently undergoing a corporate income and trade tax examination by the German tax authorities for the tax years ended March 31, 2014 through 2019. It appears reasonably possible that the amounts of unrecognized income tax benefits could change in the next twelve months upon conclusion of the Company’s current ongoing examinations; however, any potential payments of income tax, interest and penalties are not expected to be significant to the Company's consolidated financial statements. With certain exceptions, the Company is no longer subject to U.S. federal income tax examinations for tax years ending prior to March 31, 2018, state and local income tax examinations for years ending prior to March 31, 2017 or significant foreign income tax examinations for years ending prior to March 31, 2016.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share     Basic net income per share is computed by dividing net income by the corresponding weighted average number of common shares outstanding for the period. Diluted net income per share is computed based on the weighted average common shares outstanding increased by the number of incremental shares that would have been outstanding if the potential dilutive shares were issued through the exercise of outstanding stock options or release of outstanding restricted stock units and performance stock units to purchase common shares, except when the effect would be anti-dilutive. The computation of diluted net income per share for the three months ended March 31, 2021, excludes 0.2 million shares related to equity awards due to their anti-dilutive effects. The computation of diluted net income per share for the three months ended March 31, 2020 excludes 0.6 million related to equity awards due to their anti-dilutive effects.

(2) Includes unamortized debt issuance costs of $3.5 million and $3.7 million at March 31, 2021 and December 31, 2020, respectively. Senior Secured Credit Facility At March 31, 2021, the Company’s Third Amended and Restated First Lien Credit Agreement, as amended (the “Credit Agreement”), is funded by a syndicate of banks and other financial institutions and provides for (i) a $725.0 million term loan facility, which was reduced to $625.0 million as a result of a December 2019 voluntary prepayment, and (ii) a $264.0 million revolving credit facility. The term loan facility has a maturity date of August 21, 2024, and there are no required principal payments due or scheduled under the term debt until the maturity date. As of March 31, 2021 and for the three month period then ended , the borrowings under the Term Loan had a weighted-average effective interest rate of 1.86% and 1.88%, respectively. No amounts were borrowed under the revolving credit facility at March 31, 2021 or December 31, 2020; however, $0.7 million and $3.0 million of the revolving credit facility were considered utilized in connection with outstanding letters of credit at March 31, 2021 and December 31, 2020, respectively. As of March 31, 2021 , the Company was in compliance with all applicable covenants under the Credit Agreement, including compliance with a maximum permitted total net leverage ratio (the Company's sole financial maintenance covenant under the revolving credit facility discussed below) of 6.75 to 1.0. The Company's total net leverage ratio was 2.2 to 1.0 as of March 31, 2021 . 4.875% Senior Notes due 2025 On December 7, 2017, the Company issued $500.0 million aggregate principal amount of 4.875% senior notes due 2025 (the “Notes”). The Notes were issued by RBS Global, Inc. and Rexnord LLC (Company subsidiaries; collectively, the “Issuers”) pursuant to an Indenture, dated as of December 7, 2017 (the “Indenture”), by and among the Issuers, the domestic subsidiaries of the Company (with certain exceptions) as guarantors named therein (the “Subsidiary Guarantors”) and Wells Fargo Bank, National Association (the “Trustee”). The Notes are general senior unsecured obligations of the Issuers. Rexnord Corporation separately entered into a Parent Guarantee with the Trustee whereby it guaranteed certain obligations of the Issuers under the Indenture. The Notes pay interest semi-annually on June 15 and December 15. Accounts Receivable Securitization Program On September 25, 2020, certain subsidiaries of the Company entered into an accounts receivable securitization facility (the “New Securitization”) with Mizuho Bank, Ltd. (“Mizuho”) to replace the Company’s previous $100.0 million accounts receivable securitization facility with Wells Fargo & Company (the “Previous Securitization” and, collectively with the New Securitization, referred to as the “Securitization”). As part of the New Securitization, Rexnord Industries, LLC, Zurn Industries, LLC, Zurn PEX, Inc., Precision Gear LLC, Centa Corporation and Cambridge International, Inc. (collectively, the “Originators”) agreed, pursuant to an Amended and Restated Receivables Sale and Servicing Agreement, dated as of September 25, 2020 (the “Sale Agreement”), to sell all of their existing and future accounts receivable and related assets to Rexnord Funding LLC (“Rexnord Funding”), a bankruptcy-remote special purpose entity, in exchange for cash, subordinated notes and letters of credit. The Originators and Rexnord Funding intend for the transactions contemplated by the Sale Agreement to constitute true sales to Rexnord Funding by the respective Originators. In addition to being an Originator, Rexnord Industries, LLC is also the current servicer under the Sale Agreement. Concurrently with the execution of the Sale Agreement, Rexnord Funding entered into a Receivables Funding and Administration Agreement (the “Funding Agreement”) with Mizuho, as a lender and administrative agent. Pursuant to the Funding Agreement, Rexnord Funding granted Mizuho a security interest in all of its current and future receivables and related assets in exchange for a credit facility permitting borrowings of up to a maximum aggregate amount of $100.0 million outstanding from time to time. Such borrowings are being used by Rexnord Funding to finance purchases of accounts receivable from the Originators pursuant to the Sale Agreement. The amount of advances available is determined based on advance rates relating to the eligibility of the receivables held by Rexnord Funding at that time. Advances bear interest based on LIBOR plus 1.30% per annum. The last date on which advances may be made is September 24, 2021, with a six-month extension option, unless the maturity of the New Securitization is otherwise accelerated. In addition to other customary fees associated with financings of this type, Rexnord Funding pays an unused line fee of 0.40% per annum to Mizuho based on any unused portion of the New Securitization. The Securitization constitutes a “Permitted Receivables Financing” under the Company’s existing credit agreement and a “Qualified Receivables Financing” under the indenture governing the Company’s outstanding senior notes. The Securitization does not qualify for sale accounting under Accounting Standards Codification Topic 860, Transfers and Servicing. Any borrowings under the New Securitization are accounted for as secured borrowings on the Company’s consolidated balance sheets. Financing costs associated with the Securitization are recorded within “Interest expense, net” in the consolidated statements of operations if revolving loans or letters of credit are obtained under the Securitization. At March 31, 2021 and December 31, 2020, the Company's total borrowing capacity under the Securitization was $100.0 million and $85.7 million, respectively, based on the then-current accounts receivables balances. As of both March 31, 2021 and December 31, 2020, no amounts were borrowed under the Securitization. In addition, $7.5 million of available borrowing capacity under the Securitization was considered utilized in connection with outstanding letters of credit at both March 31, 2021 and December 31, 2020. As of March 31, 2021, the Company was in compliance with all applicable covenants and performance ratios contained in the Securitization. On April 16, 2021, the Company provided notice to Mizuho of its election to terminate the Funding Agreement, and other documentation related to the Securitization, effective as of May 17, 2021. In connection with the termination, the Company must reduce any outstanding principal to zero on or prior to May 17, 2021 (the outstanding principal amount was zero as of April 16, 2021), and make all other payments and pay any other fees that are due and payable under the terms of an existing fee letter between the parties, including customary commitment and program fees. See Note 11, Long-Term Debt to the audited consolidated financial statements of the Company's Transition Report on Form 10-K for the Transition Period ended December 31, 2020 for further information regarding long-term debt. Debt Commitment Letters related to Transaction with Regal In connection with the Company’s proposed transaction with Regal discussed in Note 1, on February 14, 2021, the Company entered into a debt commitment letter (the “Debt Commitment Letter”) and related fee letters with Credit Suisse AG, Cayman Islands Branch (“CS”) and Credit Suisse Loan Funding LLC, pursuant to which, and subject to the terms and conditions set forth therein, CS committed to provide up to $708.0 million in an aggregate principal amount of senior term loans under a senior secured term loan facility (“Term Loan Facility”) and up to $200.0 million in an aggregate principal amount of senior revolving loans under a senior secured revolving credit facility. The proceeds of the loans under the Term Loan Facility may be used by the Company, together with a dividend from Land Newco, Inc., a wholly-owned indirect subsidiary of the Company (“Land”) and cash on RBS Global, Inc.’s balance sheet, (a) to redeem or prepay in full (i) all obligations currently outstanding under the Credit Agreement and (ii) the 4.875% senior unsecured notes due 2025; (b) to pay fees and expenses in connection with the transactions; and (c) for general corporate purposes.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC 820, Fair Value Measurement (“ASC 820”) defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. ASC 820 also specifies a fair value hierarchy based upon the observability of inputs used in valuation techniques. Observable inputs (highest level) reflect market data obtained from independent sources, while unobservable inputs (lowest level) reflect internally developed assumptions about the assumptions a market participant would use. In accordance with ASC 820, fair value measurements are classified under the following hierarchy: • Level 1 - Quoted prices for identical instruments in active markets. • Level 2 - Quoted prices for similar instruments; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable. • Level 3 - Model-derived valuations in which one or more inputs or value-drivers are both significant to the fair value measurement and unobservable. If applicable, the Company uses quoted market prices in active markets to determine fair value, and therefore classifies such measurements within Level 1. In some cases where market prices are not available, the Company makes use of observable market based inputs to calculate fair value, in which case the measurements are classified within Level 2. If quoted or observable market prices are not available, fair value is based upon internally developed models that use, where possible, current market-based parameters. These measurements are classified within Level 3 if they use significant unobservable inputs. Fair Value of Financial Instruments The Company has a nonqualified deferred compensation plan where assets are invested in mutual funds and corporate-owned life insurance contracts held in a rabbi trust, which is restricted for payments to participants of the plan. The Company has elected to use the fair value option for the mutual funds, which are measured using quoted prices of identical instruments in active markets categorized as Level 1. Corporate-owned life insurance contracts are recorded at cash surrender value, which is provided by a third party and reflects the net asset value of the underlying publicly traded mutual funds categorized as Level 2. The deferred compensation assets are classified within other assets on the condensed consolidated balance sheets. Deferred compensation liabilities are measured at fair value based on quoted prices of identical instruments to the investment vehicles selected by the participants categorized as Level 1. Deferred compensation liabilities are classified within other liabilities on the condensed consolidated balance sheets. The following table provides a summary of the Company's assets and liabilities that were recognized at fair value on a recurring basis as of March 31, 2021 and December 31, 2020 (in millions): Fair Value as of March 31, 2021 Level 1 Level 2 Level 3 Total Deferred compensation assets $ 2.5 $ 10.8 $ — $ 13.3 Deferred compensation liabilities 13.7 — — 13.7 Fair Value as of December 31, 2020 Level 1 Level 2 Level 3 Total Deferred compensation assets $ 1.0 $ 10.7 $ — $ 11.7 Deferred compensation liabilities 11.9 — — 11.9 There were no transfers of assets between levels at March 31, 2021 and December 31, 2020, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Warranties: The Company offers warranties on the sales of certain products and records an accrual for estimated future claims. Such accruals are based upon historical experience and management's estimate of the level of future claims. The following table presents changes in the Company's product warranty liability (in millions): Three Months Ended March 31, 2021 March 31, 2020 Balance at beginning of period $ 8.9 $ 6.3 Acquired obligations 0.3 — Charged to operations 0.6 1.2 Claims settled (1.3) (0.8) Balance at end of period $ 8.5 $ 6.7 Contingencies: The Company's subsidiaries are involved in various unresolved legal actions, administrative proceedings and claims in the ordinary course of business involving, among other things, product liability, commercial, employment, workers' compensation, intellectual property claims and environmental matters. The Company establishes accruals in a manner that is consistent with accounting principles generally accepted in the United States for costs associated with such matters when liability is probable and those costs are capable of being reasonably estimated. Although it is not possible to predict with certainty the outcome of these unresolved legal actions or the range of possible loss or recovery, based upon current information, management believes the eventual outcome of these unresolved legal actions, either individually or in the aggregate, will not have a material adverse effect on the financial position, results of operations or cash flows of the Company. In connection with its sale, Invensys plc ("Invensys") provided the Company with indemnification against certain contingent liabilities, including certain pre-closing environmental liabilities. The Company believes that, pursuant to such indemnity obligations, Invensys is obligated to defend and indemnify the Company with respect to the matters described below relating to the Ellsworth Industrial Park Site and to various asbestos claims. The indemnity obligations relating to the matters described below are subject, together with indemnity obligations relating to other matters, to an overall dollar cap equal to the purchase price, which is an amount in excess of $900 million. The following paragraphs summarize the most significant actions and proceedings: • In 2002, Rexnord Industries, LLC ("Rexnord Industries") was named as a potentially responsible party ("PRP"), together with at least ten other companies, at the Ellsworth Industrial Park Site, Downers Grove, DuPage County, Illinois (the "Site"), by the United States Environmental Protection Agency ("USEPA"), and the Illinois Environmental Protection Agency ("IEPA"). Rexnord Industries' Downers Grove property is situated within the Ellsworth Industrial Complex. The USEPA and IEPA allege there have been one or more releases or threatened releases of chlorinated solvents and other hazardous substances, pollutants or contaminants, allegedly including but not limited to a release or threatened release on or from the Company's property, at the Site. The relief sought by the USEPA and IEPA includes further investigation and potential remediation of the Site and reimbursement of USEPA's past costs. In early 2020, Rexnord Industries entered into an administrative order with the USEPA to do remediation work on its Downers Grove property. The remediation work started in 2020 and is on-going. Rexnord Industries' allocated share of past and future costs related to the Site, including for investigation and/or remediation, could be significant. All previously pending property damage and personal injury lawsuits against the Company related to the Site have been settled or dismissed. Pursuant to its indemnity obligation, Invensys continues to defend the Company in known matters related to the Site, including the costs of the remediation work pursuant to the 2020 administrative order, and has paid 100% of the costs to date. • Multiple lawsuits (with approximately 300 claimants) are pending in state or federal court in numerous jurisdictions relating to alleged personal injuries due to the alleged presence of asbestos in certain brakes and clutches previously manufactured by the Company's Stearns division and/or its predecessor owners. Invensys and FMC, prior owners of the Stearns business, have paid 100% of the costs to date related to the Stearns lawsuits. Similarly, the Company's Prager subsidiary is the subject of claims by multiple claimants alleging personal injuries due to the alleged presence of asbestos in a product allegedly manufactured by Prager. However, all these claims are currently on the Texas Multi-district Litigation inactive docket, and the Company does not believe that they will become active in the future. To date, the Company's insurance providers have paid 100% of the costs related to the Prager asbestos matters. The Company believes that the combination of its insurance coverage and the Invensys indemnity obligations will cover any future costs of these matters. In connection with the Company's acquisition of The Falk Corporation ("Falk"), Hamilton Sundstrand provided the Company with indemnification against certain products-related asbestos exposure liabilities. The Company believes that, pursuant to such indemnity obligations, Hamilton Sundstrand is obligated to defend and indemnify the Company with respect to the asbestos claims described below, and that, with respect to these claims, such indemnity obligations are not subject to any time or dollar limitations. The following paragraph summarizes the most significant actions and proceedings for which Hamilton Sundstrand has accepted responsibility: • Falk, through its successor entity, is a defendant in multiple lawsuits pending in state or federal court in numerous jurisdictions relating to alleged personal injuries due to the alleged presence of asbestos in certain clutches and drives previously manufactured by Falk. There are approximately 100 claimants in these suits. The ultimate outcome of these lawsuits cannot presently be determined. Hamilton Sundstrand is defending the Company in these lawsuits pursuant to its indemnity obligations and has paid 100% of the costs to date. Certain Water Management subsidiaries are also subject to asbestos litigation. As of March 31, 2021, Zurn and numerous other unrelated companies were defendants in approximately 6,000 asbestos related lawsuits representing approximately 7,000 claims. Plaintiffs' claims allege personal injuries caused by exposure to asbestos used primarily in industrial boilers formerly manufactured by a segment of Zurn. Zurn did not manufacture asbestos or asbestos components. Instead, Zurn purchased them from suppliers. These claims are being handled pursuant to a defense strategy funded by insurers. As of March 31, 2021, the Company estimates the potential liability for the asbestos-related claims described above as well as the claims expected to be filed in the next ten years to be approximately $59.0 million, of which Zurn expects its insurance carriers to pay approximately $42.0 million in the next ten years on such claims, with the balance of the estimated liability being paid in subsequent years. The $59.0 million was developed based on actuarial studies and represents the projected indemnity payout for current and future claims. There are inherent uncertainties involved in estimating the number of future asbestos claims, future settlement costs, and the effectiveness of defense strategies and settlement initiatives. As a result, actual liability could differ from the estimate described herein and could be substantial. The liability for the asbestos-related claims is recorded in Other liabilities within the condensed consolidated balance sheets. Management estimates that its available insurance to cover this potential asbestos liability as of March 31, 2021, is in excess of the 10 year estimated exposure, and accordingly, believes that all current claims are covered by insurance. As of March 31, 2021, the Company had a recorded receivable from its insurance carriers of $59.0 million, which corresponds to the amount of this potential asbestos liability that is covered by available insurance and is currently determined to be probable of recovery. However, there is no assurance the Company's current insurance coverage will ultimately be available or that this asbestos liability will not ultimately exceed the Company's coverage limits. Factors that could cause a decrease in the amount of available coverage or create gaps in coverage include: changes in law governing the policies, potential disputes and settlements with the carriers regarding the scope of coverage, and insolvencies of one or more of the Company's carriers. The receivable for probable asbestos-related recoveries is recorded in Other assets within the condensed consolidated balance sheets. Certain Company subsidiaries were named as defendants in a number of individual and class action lawsuits in various United States courts claiming damages due to the alleged failure or anticipated failure of Zurn brass fittings on the PEX plumbing systems in homes and other structures. In fiscal 2013, the Company reached a court-approved agreement to settle the liability underlying this litigation. The settlement was designed to resolve, on a national basis, the Company's overall exposure for both known and unknown claims related to the alleged failure or anticipated failure of such fittings. The settlement utilized a seven year claims fund, which was capped at $20.0 million, and was funded in installments over the seven year period based on claim activity and minimum funding criteria. The seven year filing period expired on April 1, 2020. Any claims after April 1, 2020 are time barred. The Company expects to make payment on any remaining timely filed claims and close out the settlement fund. The Company has recorded an accrual for the balance of this liability.

Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate that is expected to be discontinued because of reference rate reform. The amendments in this update provide optional expedients and exceptions for applying GAAP to instruments affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in this ASU are effective for all entities as of March 12, 2020, In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ( "ASU 2019-12" )
Revenue Recognition	Revenue Recognition A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC 606, Revenue from Contracts with Customers ("ASC 606"). A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized when obligations under the terms of a contract with the customer are satisfied. For the majority of the Company's product sales, revenue is recognized at a point-in-time when control of the product is transferred to the customer, which generally occurs when the product is shipped from the Company's manufacturing facility to the customer. When contracts include multiple products to be delivered to the customer, generally each product is separately priced and is determined to be distinct within the context of the contract. Other than a standard assurance-type warranty that the product will conform to agreed-upon specifications, there are generally no other significant post-shipment obligations. The expected costs associated with standard warranties continues to be recognized as an expense when the products are sold. When the contract provides the customer the right to return eligible products or when the customer is part of a sales rebate program, the Company reduces revenue at the point of sale using current facts and historical experience by using an estimate for expected product returns and rebates associated with the transaction. The Company adjusts these estimates at the earlier of when the most likely amount of consideration that is expected to be received changes or when the consideration becomes fixed. Accordingly, an increase or decrease to revenue is recognized at that time. Sales and other taxes collected concurrent with revenue-producing activities are excluded from revenue. The Company has elected to recognize the cost for freight and shipping when control of products has transferred to the customer as a component of cost of sales in the condensed consolidated statements of operations. The Company classifies shipping and handling fees billed to customers as net sales and the corresponding costs are classified as Cost of sales in the condensed consolidated statements of operations. Timing of Performance Obligations Satisfied at a Point in Time The Company determined that the customer is able to control the product when it is delivered to them; thus, depending on the shipping terms, control will transfer at different points between the Company's manufacturing facility or warehouse and the customer’s location. The Company considers control to have transferred upon shipment or delivery because the Company has a present right to payment at that time, the customer has legal title to the asset, the Company has transferred physical possession of the asset, and the customer has significant risks and rewards of ownership of the asset. Variable Consideration The Company provides volume-based rebates and the right to return product to certain customers, which are accrued for based on current facts and historical experience. Rebates are paid either on an annual or quarterly basis. There are no other significant variable consideration elements included in the Company's contracts with customers. Contract Costs The Company has elected to expense contract costs as incurred if the amortization period is expected to be one year or less. If the amortization period of these costs is expected to be greater than one year, the costs would be subject to capitalization. As of March 31, 2021, the contract assets capitalized, as well as amortization recognized in the three months ended March 31, 2021, are not significant and there have been no impairment losses recognized.
