                DUE 2012

Ladies and Gentlemen:

          In connection with the registration of $225,000,000 aggregate
principal amount of 10-1/8% Senior Subordinated Notes due 2012 (the
"Securities") by Rexnord Corporation, a Delaware corporation (the "Company") and
each of the co-registrants, the guarantees of the Securities (the "Guarantees")
by each of the entities listed on Schedule A hereto (the "Guarantors"), and
specifically that certain guaranty of the Securities (the "Covered Guaranty") by
Addax, Inc., a Nebraska corporation (the "Covered Guarantor"), under the
Securities Act of 1933, as amended (the "Act"), on Form S-4 filed with the
Securities and Exchange Commission (the "Commission") on January 9, 2003,
and amended on March 19, 2003, April 17, 2003, May 14, 2003 and May 15, 2003

          In our capacity as special counsel to the Covered Guarantor, in
connection with such registration, we are familiar with the proceedings taken by
the Covered Guarantor in connection with the authorization and issuance of the
Covered Guaranty, and have reviewed a signed copy of the Covered Guaranty
bearing the signature of Thomas J. Jansen.

          In addition, we have examined originals or copies certified or
otherwise identified to our satisfaction of the following documents:

          (a)     the Articles of Incorporation of Addax, Inc., as filed with
                  the Nebraska Secretary of State on November 13, 1985;

          (b)     the Bylaws of Addax, Inc.;

          (c)     the Certificate of Good Standing with respect to the Covered
                  Guarantor from the Nebraska Secretary of State dated March 11,
                  2003 (the "Certificate of Good Standing");

          (d)     the Written Consent in Lieu of a Special Meeting of the
                  Directors of Addax, Inc., dated November 25, 2002 (the
                  "Appointment Consent"); and

          (e)     the Written Consent in Lieu of a Special Meeting of the Board
                  of Directors of Addax, Inc., dated November 25, 2002 (the
                  "Directors' Consent").

          The documents described in (a) through (e) above are collectively
referred to herein as the "Corporate Documents". With respect to all factual
matters, we have relied solely upon, and have assumed the accuracy, completeness
and genuineness of, the representations, warranties and certificates contained
in and made pursuant to, the Operative Documents and the Corporate Documents.

         We have not served as general counsel for any of the parties to, nor
have we been involved in the transactions contemplated in, the Operative
Documents. We have represented the Covered Guarantor only with respect to the
rendering of this opinion.

          In rendering the opinions set forth below, we have relied, with your
permission, upon the following specific assumptions, the accuracy of which we
have not independently verified:

          (a)     Except for the Operative Documents, there are no other
                  documents or agreements executed by or between any of the
                  parties that would expand or otherwise modify the obligations
                  of the Covered Guarantor under the Covered Guaranty or that
                  would have any effect on the opinion rendered herein;

          (b)     In our examination, we have assumed the genuineness of all
                  signatures, the authenticity of all documents submitted to us
                  as originals, and the conformity to authentic original
                  documents of all documents submitted to us as copies; and

          (c)     the Bylaws of the Covered Guarantor that have been provided to
                  us are the current Bylaws of the Covered Guarantor, and there
                  have been no Amendments to such Bylaws that would have any
                  effect on the opinion rendered herein;


                                       2

          We are opining herein as to the effect on the subject transaction only
of the laws of the State of Nebraska, and we express no opinion with respect to
the applicability thereto, or the effect thereon, of the laws of any other
jurisdiction, including the federal laws of the United States, or as to any
matters of municipal law or the laws of any local agencies within any state.

          Subject to the foregoing and the other matters set forth herein, it is
our opinion that as of the date hereof:

          (1)     The Covered Guaranty to be executed and delivered by the
                  Covered Guarantor set forth in the Indenture has been duly
                  authorized by all necessary corporate action of the Covered
                  Guarantor, and the Covered Guaranty has been duly executed and
                  delivered by the Covered Guarantor.

          To the extent that the obligations of the Company and each Guarantor
under the Operative Documents may be dependent upon such matters, we assume for
purposes of this opinion that each Guarantor other than the Covered Guarantor:
(a) is duly organized, validly existing and in good standing under the laws of
its jurisdiction of organization; (b) has the requisite organizational and legal
power and authority to perform its obligations under each of the Operative
Documents to which it is a party; (c) is duly qualified to engage in the
activities contemplated by each such Operative Document; and (d) has duly
authorized, executed and delivered each such Operative Document.

          We consent to your filing this opinion as an exhibit to the
Registration Statement and to the reference to our firm contained under the
heading "Legal Matters" contained in the prospectus contained therein.


                                               Very truly yours,

                                               /s/ Thomas R. Ostdiek

                                               THOMAS R. OSTDIEK
