                                  PART  I

ITEM 1.   Business

General Development of Business
- -------------------------------
Regal-Beloit Corporation is a Wisconsin corporation founded in 1955.  The
Company's initial business was the production of special metalworking taps.
Through 34 acquisitions and internal growth, the Company has become a
prominent manufacturer of a diversified line of mechanical products to
control motion and torque and electrical products such as motors and
generators.

The Company's mechanical products are manufactured by its Mechanical Group
and include standard and custom worm gear, bevel gear, helical gear and
concentric shaft gearboxes; marine and high-performance after-market
automotive transmissions; custom gearing; gear motors; manual valve actuators;
and perishable, high speed steel, rotary cutting tools.  Mechanical Group
products are sold to distributors, original equipment manufacturers and end
users across many industry segments.

Typical applications for the Company's mechanical products include material
handling systems such as conveyors, palletizers and packaging equipment;
off-highway vehicular equipment such as street pavers, graders,
airport/fire/crash/rescue equipment; farm implements; gas and liquid pipeline
transmission systems; civic water and waste treatment facilities; open-pit
mining; paper making machinery;  high-performance, after-market automotive
transmissions and ring/pinion sets;  and marine transmissions for luxury
inboard powered craft.

Effective March 26, 1997, the Company acquired 100% of the stock of Marathon
Electric Manufacturing Corporation. Marathon Electric now comprises the
Company's Electrical Group. The Electrical Group produces and markets AC
electric motors ranging in size from 1/12 horsepower to over 500 horsepower
and electric generators ranging in size from 5 kilowatts through 2300
kilowatts.  The Group is currently developing larger motors to 800 horsepower
and larger generators to 4,000 kilowatts, and plans to commence shipments in
the second and third quarters of 1999, respectively.  The Group's products
are also sold to distributors, original equipment manufacturers and end users
across many industry segments.

Typical applications for the Company s electrical products include: 1) for
electric motors: air movement such as heating, ventilating, air conditioning
and compressors;  fluid movement such as pumping; woodworking; commercial
laundry; process industries; variable frequency drives; and floor care; and
2) for electric generators: prime and standby power applications including
buildings such as telecommunication, commercial, industrial, hospital and
school; marine; agriculture; windpower; military; and transport refrigeration.

Regal-Beloit believes its consistent ability to provide products on a shorter
delivery schedule than other manufacturers gives it a competitive selling
advantage and that its extensive use of modern, up-to-date equipment which
is best suited for the job, along with its continued product redesign and
effective plant layout, often gives it a competitive cost advantage in its
product offering.

Marketing and Sales
- -------------------
The Company's products are sold to distributors, original equipment
manufacturers and end users.  Both the Mechanical Group and the Electrical
Group have their own organization of field sales employees and manufacturers 
representatives.



Export sales accounted for approximately 6% of the Company's sales in 1998,
7% in 1997 and 3% in 1996.  Additionally, 3%, 4%, and 7% of Company sales
were manufactured and sold outside the United States in 1998, 1997, and 1996,
respectively.  No material part of the Company's business is dependent upon
a single customer.  In fiscal 1998, 1997, and 1996, no single customer
accounted for as much as 3% of Company sales.  Although the Company's sales
are predominantly not seasonal, they tend to vary with general economic
conditions and with the rate of industrial production, and  are affected by
business climates in the many markets in which the Company sells.  However,
because the Company's products are sold to many different markets, the
effects of weaker markets are frequently offset by strengths in other markets.

Working capital requirements to properly serve the Company's customers are
generally typical of capital goods manufacturers.  Accounts receivable and
inventory are generally not seasonal or at unusual levels by industry
standards.

Competition
- -----------
Major domestic competitors in the mechanical motion control equipment industry
include Emerson Electric, Reliance Electric, Winsmith, Falk, and Boston Gear.
Major foreign competitors would include SEW Eurodrive, Flender, Sumitomo and
Zahnrad Fabrik.  Major domestic competitors for the Electrical Group include
Baldor Electric, Emerson, Reliance, Leeson, General Electric, Cummins,
and Magnetek.  Major foreign competitors include Siemens, Toshiba, Weg,
Leroy Somer, and ABB.

Over the past several years, niche product market opportunities have become
more prevalent due to changing market conditions.  The Mechanical Group's
markets have also been impacted by decisions by larger manufacturers not to
compete in lower volume or specialized markets. Many captive producers have
chosen, for economic reasons, to outsource their requirements to specialized
manufacturers like Regal-Beloit's Mechanical Group, who can produce more cost
effectively.

The Company has capitalized on this competitive climate by making acquisitions
and increasing its manufacturing efficiencies.  Some of these acquisitions
have created new opportunities for the Company because the Company is now in
new markets in which it was not previously involved.  The Company has also
continued to upgrade its manufacturing equipment and processes, including
increasing its use of computer aided manufacturing systems and redesigning
products to take full advantage of the more productive equipment along with
redoing plant layout to improve product flow.  In practice, the Company's
operating units have sought out specific niche markets concentrating on a
wide diversity of customers and applications.  Because of this approach, the
Company is often not the largest supplier in any specific market. The Company
believes it  competes primarily on the basis of the promptness of delivery,
price and quality.

For further segment information required by Item 101 of Regulation S-K,
reference is made to Note 11 of Notes to Consolidated Financial Statements
on page 14 of the Annual Report to Shareholders for the year ended
December 31, 1998, and such information is incorporated herein by reference.

Manufacturing
- -------------
Each of the Company's operating units conducts its manufacturing operations
independently in one or more facilities.  The Company regularly invests in
high quality machinery and equipment and other improvements to and
maintenance of its facilities.  These capital expenditures typically meet

4

or exceed the Company's depreciation levels, as the Company believes that
such investments are essential to its long-term success, although in 1998
expenditures were held below depreciation as the capital goods economy
slowed.

The manufacturing operations of both the Mechanical Group and Electrical
Group are highly integrated.  Although raw materials and selected parts
such as bearings and seals are purchased, this vertical integration permits
the Company to produce most of its products  component parts when needed.
The Company believes this results in lower production costs, greater
manufacturing flexibility and higher product quality, as well as reducing
the Company's reliance on outside suppliers.

Base materials for the Company's products consist primarily of: 1) steel in
various types and sizes, bearings and weldments, 2) copper magnet wire and
3) castings made of grey iron or aluminum.  The Company purchases its raw
materials from many suppliers and is not dependent on any single supplier
for any of its base materials.

Backlog
- -------
As of December 31, 1998, the amount of the Company's Mechanical Group
backlog was approximately $40,300,000 compared to approximately $51,310,000
on December 31, 1997.  The Electrical Group backlog as of December 31, 1998
was $25,300,000 versus $31,700,000 on December 31, 1997.  Average delivery
time for orders of the Company's mechanical products (except for large,
specially designed products) varies from three days to two months.  The
Company believes that virtually all of its backlog is shippable in 1999.
The Company's business units have historically shipped the majority of its
products in the month the order is received.  Accordingly, since total
backlog is less than 15% of the Company's annual sales, the Company believes
that backlog is not a reliable indicator of the Company's future sales.

Patents, Trademarks and Licenses
- --------------------------------
The Company owns a number of United States patents and foreign patents
relating to its businesses.  While the Company believes that its patents
provide certain competitive advantages, the Company does not consider any one
patent or group thereof essential to the business of either of its Groups or
the Company as a whole.  Regal-Beloit utilizes various registered and
unregistered trademarks and the Company believes these trademarks are
significant in the marketing of most of its products.  However, the Company
believes the successful manufacture and sale of its products generally
depends more upon its technological, manufacturing and marketing skills.
In addition, the Company believes its engineering, test and development
capabilities are significant factors in the success of its business.

Employees
- ---------
As of December 31, 1998, the Company employed approximately 4,780 persons,
of which approximately 27% are covered by collective bargaining agreements.
The Company considers its employee relations to be very good.

Environmental Matters
- ---------------------
The Company is subject to Federal, State and local environmental regulations.
The Company is currently involved with environmental proceedings related to
certain of its facilities.  Based on available information, it is believed
that the outcome of these proceedings and future known environmental
compliance costs will not have a material adverse effect on the Company's
financial position or results of operations.

2.  EFFECTIVE DATE.  The 1998 Plan is effective as of April 21, 1998, subject
    to the approval by the holders of at least a majority of the outstanding
    shares of the Company's Common Stock, present, or represented, and

4.  ADMINISTRATION OF THE 1998 PLAN.  The 1998 Plan shall be administered by
    the Board of Directors of the Company or a Committee comprised of two or
    more Non-Employee Directors, (hereinafter collectively called the
    "Committee").  The Committee shall have all the powers vested in it by
    the terms of the 1998 Plan, such powers to include exclusive authority
    (within the limits described herein) to select the eligible Participants
    (as hereinafter defined) to receive Grants under the 1998 Plan, to
    determine the type, size and terms of Grants to be made to each
    Participant selected, to determine the time when Grants will be granted
    and to establish objectives and conditions, if any, relating to such
    Grants.  The Committee shall have full power and authority to administer
    and interpret the 1998 Plan and to adopt such rules, regulations,
    agreements, guidelines and instruments for the administration of the
    1998 Plan and to make all other determinations which the Committee deems
    necessary or advisable.  The Committee's interpretation of the 1998 Plan
    and all actions taken and determinations made by the Committee pursuant
    to the powers vested in it hereunder, shall be conclusive and binding on
    all parties concerned, including the Company, its Shareholders and
    Participants in the 1998 Plan.

    In administering the 1998 Plan, the term "Committee" shall mean
    exclusively the Board of Directors where appropriate when interpreting
    the 1998 Plan as it pertains to Non-Employee Directors. "Non Employee
    Directors" means those Outside Directors who are not officers or employees
    of the Company.

5.  ELIGIBLE PARTICIPANTS.  The persons eligible to participate in the 1998
    Plan shall be all Directors, Officers, key executives and other management
    employees of the Company who are responsible for or contribute to the
    management, growth and/or profitability of the business of the Company
    (the "Participants").

6.  NON-EMPLOYEE DIRECTOR GRANTS.

    a. (i) The 1998 Plan shall supersede the 1991 Flexible Stock Incentive
       Plan, as amended, as to Non-Employee Director grants only, effective
       April 21 1998.

1
       (ii)  Under the 1998 Plan, each individual Non-Employee Director will
       be annually granted stock options, Stock Appreciation Rights or any
       combination thereof of shares of Common Stock at 100 percent (100%)
       of the fair market value as of the date corresponding to the Annual
       Shareholders' Meeting.  For the years 1998 and 1999, each individual
       Non-Employee Director shall be granted 800 shares of Common Stock.
       For the years 2000 and 2001, each individual Grant will be increased
       to 900 shares.  For the years 2002 through 2008, each individual Grant
       will be increased to 1,000 shares.  However, the first Grant to each
       Non-Employee Director who is initially elected as a Non-Employee
       Director or is initially appointed subsequent to the date of the
       Annual Shareholders' Meeting of the Company and prior to the date of
       the next succeeding Annual Shareholders' Meeting, shall be three (3)
       times the number of shares granted to each individual Non-Employee
       Director during such applicable year at 100 percent (100%) of the fair
       market value at the closing sale price on the date that he or she
       becomes a director of the Company.

    b. The right to exercise any Grant given to Non-Employee Directors shall
       vest immediately upon Grant. Unexercised Grants to Non-Employee
       Directors shall terminate the earlier of ten (10) years after the date
       of Grant or ninety (90) days after the Non-Employee Director ceases to
       be a member of the Company's Board of Directors, unless terminated for
       Cause as provided in Section 18.

    c. In all other respects, Grants to a Non-Employee Director under the
       Plan shall be controlled by the terms and conditions of the 1998 Plan
       and the rules, regulations, agreements, guidelines, instruments and
       interpretations issued by the Committee, except where inconsistent
       with the limitations set forth in this Section 6 of the 1998 Plan.

 7. GRANTS.

    a. Types.  Grants under the 1998 Plan shall be made with reference to
       -----
       shares of the Company's Common Stock and may include, but need not be
       limited to Incentive Stock Options ("ISO"), Nonqualified Stock Options
       ("NSO"), Restricted Stock, Deferred Stock, Stock Appreciation Rights
       or any combination thereof.
  
    b. Vesting
       -------

       (i)  The Committee, in its sole discretion, shall determine any vesting
       (i.e., exercisability) requirements applicable to each Grant.

       (ii)  The Committee may also determine that all or a portion of a
       payment of Grants other than ISOs and NSOs to a Participant under the
       1998 Plan, whether it is to be made in cash, shares of the Company's
       Common Stock or a combination thereof, shall be vested at such times
       and upon such terms as may be selected by it in its sole discretion.

    c. Price.  The option price per share of each option granted shall be
       -----
       established by the Committee except that the option price shall not be
       less than 100 percent (100%) of the fair market value of the stock at
       the closing sale price on the date the option is granted.  If there is
       no sale on the date of Grant, the fair market value of the stock shall
       be the closing sale price of the stock on the preceding business day
       on which the Company's Common Stock was traded.

    d. Performance Goals.  The Committee may, but need not, establish
       -----------------
       performance goals to be achieved within such performance periods as
       may be selected by it in its sole discretion, using such measures of
       the performance of the Company as it may select.

    e. Guidelines.  The Committee may adopt from time to time written policies
       ----------
       implementing the 1998 Plan. Such policies may include, but need not be
       limited to the type, size and term of Grants to be made to Participants
       and the conditions for payment of such Grants.

2
    f. Maximum Grants.  Participants may be granted multiple Grants under the
       --------------
       1998 Plan.  However, no one Participant shall be granted a Grant if
       immediately after such Grant he or she is the owner or would be deemed
       to be the owner of more than 10 percent (10%) of the total combined
       voting power of all classes of stock of the Company, unless the option
       price per share is at least 110 percent (110%) of the fair market value
       and such Grant by its terms is not exercisable after the expiration of
       five (5) years from the date such Grant is granted.

 8. PAYMENT OF GRANTS.

    The Committee shall determine the extent to which Grants other than ISOs
    and NSOs shall be payable in cash, shares of the Company's Common Stock
    or any combination thereof to a Participant.  The Committee may
    determine that all or a portion of a payment to a Participant under the
    1998 Plan, whether it is to be made in cash, shares of the Company's
    Common Stock or a combination thereof shall be deferred.  Deferrals
    shall be for such periods and upon such terms as the Committee may
    determine in its sole discretion.

 9. EXERCISE OF ISOs AND NSOS.  The price for shares may be paid in any
    combination of cash, cashier's or certified check, personal check
    acceptable to the Company, or shares of the Company's Common Stock,
    including previously owned Common Stock.

10. RIGHTS OF SHAREHOLDERS.  A Participant under the 1998 Plan shall have no
    rights as a holder of the Company's Common Stock with respect to Grants
    hereunder, unless and until certificates for shares of such stock are
    issued to the Participant.

11. ASSIGNMENT OR TRANSFER.  Except as otherwise provided by the Committee,
    Grants under the 1998 Plan or any rights or interests therein shall not
    be assignable or transferable except by will or the laws of descent and
    distribution, or exercisable by anyone other than the Participant during
    his or her lifetime.

12. AGREEMENTS.  All Grants granted under the 1998 Plan shall be evidenced by
    agreements in such form and containing such terms and conditions (not
    inconsistent with the 1998 Plan) as the Committee shall adopt.

13. COMPLIANCE WITH LEGAL REGULATIONS.

    a. The Committee may require each person purchasing shares pursuant to a
       stock option or other Grant under the 1998 Plan to represent to and
       agree with the Company in writing that the optionee or Participant is
       acquiring the shares without a view to distribution thereof.  The
       certificates for such shares may include any legend which the Committee
       deems appropriate to reflect any restrictions on transfer.

    b. All certificates for shares of stock or other securities delivered
       under the 1998 Plan shall be subject to such stock transfer orders and
       other restrictions as the Committee may deem advisable under the rules,
       regulations and other requirements of the Securities and Exchange
       Commission, any stock exchange upon which the stock is then listed,
       and any applicable federal or state securities law, and the Committee
       may cause a legend or legends to be put on any such certificate to make
       appropriate reference to such restrictions.

14. WITHHOLDING TAXES.

    a. The Company shall have the right to deduct from all Grants hereunder
       paid in cash any federal, state, local or foreign taxes required by
       law to be withheld with respect to such Grants.

    b. With respect to Grants paid by shares of the Company's Common Stock,
       the Company shall also have the right to require the payment (through
       withholding from the Participant's salary or otherwise) of any of the
       taxes referenced above in Section 14a.  An appropriate number of
       shares of Common Stock may be withheld for such payment.  If shares
       are used to satisfy tax withholding requirements, the value of such
       shares shall be based on the fair market value of the Common Stock on
       the date when the tax withholding is required to be made.

    c. The obligation of the Company to make delivery of Grants in cash or the
       Company's Common Stock shall be subject to currency or other
       restrictions imposed by any government.

3
15. NO RIGHTS TO GRANTS.  No Participant or other person shall have any right
    to receive a Grant under the 1998 Plan.  Neither the 1998 Plan nor any
    action taken hereunder shall be construed as giving any Participant any
    right to be retained in the employ of the Company or any of its
    subsidiaries or shall interfere with or restrict in any way the rights of
    the Company, which are hereby reserved, to discharge the Participant at
    any time for any reason whatsoever, with or without good cause.

16. COST AND EXPENSES.  The cost and expense of administering the 1998 Plan
    shall be bome by the Company and not charged to any Grant nor to any
    Participant receiving a Grant.

17. TERMINATION OR EXPIRATION OF GRANTS.  If any Grant under the 1998 Plan
    terminates or expires, the shares allocable to the unexercised portion
    of the Grant will be available for purposes of the 1998 Plan.  In certain
    circumstances where a Participant uses stock to exercise a Grant, only
    the net shares issued to the Participant are counted against the number
    of shares issued under the 1998 Plan.  Certain stock issuances which are
    later forfeited by the Participant do not count as grants under the 1998
    Plan.

18. TERMINATION OF EMPLOYMENT.

    a. (i)  In the event a Participant's employment with the Company is
       terminated, whether voluntarily or otherwise, but not by reason of
       death, disability or retirement, each prior unexpired or uncancelled
       Grant, to the extent exercisable as of the date of such termination of
       employment or service, shall terminate thirty (30) days after the
       Participant's date of termination or as determined by the Committee.
    
       (ii)  Notwithstanding the foregoing, if a Participant's employment or
       service as a Non-Employee Director of the Company is terminated for
       Cause (as defined below), each unexpired or uncancelled Grant, to the
       extent not previously exercised by him or her, shall terminate
       immediately.
    
    b. The term "Cause" is defined as: (i) the commission by a Participant of
       any act or omission that would constitute a felony under federal,
       state or equivalent foreign law, (ii) fraud, dishonesty, theft,
       embezzlement, disclosure of trade secrets or confidential information
       or other acts or omissions that result in a breach of any fiduciary
       duty to the Company.
    
    c. In the event a Participant terminates his or her employment with the
       Company as a result of death, disability, or retirement, the Committee
       shall have the discretion to extend the period of exercisability of
       each previously granted and unexpired or uncancelled Grant in
       accordance with applicable statutes, rules and regulations and to
       preserve ISO treatment, where necessary, unless the termination date
       specified in the Grant occurs earlier.  The Committee shall also have
       discretion to determine whether such Grant(s) shall become immediately
       exercisable in full.


19. DILUTION AND OTHER ADJUSTMENTS.  In the event of any change in the
    outstanding shares of the Company's Common Stock by reason of any split,
    stock dividend, recapitalization, merger, consolidation, combination or
    exchange of shares or other similar corporate change, such equitable
    adjustments shall be made in the 1998 Plan and the Grants thereunder as
    the Committee determines are necessary or appropriate.  If necessary, the
    Committee may make any adjustments in the maximum number of shares
    referred to in Section 3, in the number and option price of shares
    subject to outstanding options, in the number and purchase price of
    shares subject to outstanding stock purchase rights, and in the number of
    shares subject to other Grants granted under the 1998 Plan.  Such
    adjustment shall be conclusive and binding for all purposes of the
    1998 Plan.

20. AMENDMENTS AND TERMINATIONS.

    a. Amendments.  The Committee may terminate or amend the 1998 Plan in
       whole or in part at any time, but no such action shall adversely
       affect any rights or obligations with respect to any Grants theretofore
       made under the 1998 Plan nor change the limitations as to Non-Employee
       Directors as set forth in Section 6 hereof.

4

       Unless the holders of at least a majority of the outstanding shares of
       the Common Stock, present or represented, and entitled to vote at a
       meeting of Shareholders shall have first approved thereof, no amendment
       of the 1998 Plan shall be effective which would (i) increase the
       maximum number of shares referred to in Section 3 of the 1998 Plan;
       (ii) extend the maximum period during which ISO Grants may be granted
       under the 1998 Plan, or (iii) reduce the price per share at which ISO
       Options may be offered under the 1998 Plan below 100 percent (100%) of
       the fair market value on the date of Grant.  For purposes of this
       Section 20a, subject to adjustment as provided in Section 19, any (1)
       cancellation and reissuance or (2) repricing of any Grants made under
       the 1998 Plan at a new option price as provided in the 1998 Plan's
       rules relating to stock options and Stock Appreciation Rights shall
       not constitute an amendment of this 1998 Plan.
    
       With the consent of the Participant affected, the Committee or the
       Board of Directors, where applicable, may amend outstanding agreements
       evidencing Grants under the 1998 Plan in a manner not inconsistent
       with the terms of the 1998 Plan.

    b. Termination.  Unless the 1998 Plan shall heretofore have been
       terminated as above provided, the 1998 Plan shall terminate on and no
       Grants shall be granted after April 20, 2008.  Any Grants outstanding
       under the 1998 Plan at the time of the termination of the 1998 Plan
       shall remain in effect until such Grant shall have been exercised or
       shall have expired according to its terms.

21. GOVERNING LAWS.  The validity and construction of the 1998 Plan and any
    agreements entered into thereunder shall be governed by the laws of the
    State of Wisconsin.

22. COMPLIANCE WITH APPLICABLE LAWS.  The Committee will comply with all
    applicable laws, rules and regulations including the Internal Revenue
    Code of 1986, as amended (the "Code") and the Securities Exchange Act of
    1934, as amended (the "Exchange Act") or any successor provisions or other
    regulatory requirements.  To the extent required, the 1998 Plan is
    designed to comply with Section 162(m) of the Code to qualify future
    performance based compensation and to qualify under Section 16 of the
    Exchange Act.  To the extent any provision of the 1998 Plan or action by
    the Committee fails to so comply,  it shall be deemed null and void to
    the extent permitted by law and deemed advisable by the Committee.
