Re: Albany International Corp. Registration Statement on FormS-3

Ladies and Gentlemen:

We have acted as special counsel to Albany International Corp., a Delaware corporation (the “Company”), in connection with the offering by Standish Family Holdings LLC and J.S. Standish Co. (together, the “Selling Stockholders”) pursuant to a registration statement on FormS-3 (No.333-231776) of 1,616,000 shares of Class A common stock of the Company, par value $0.001 per share, of which 1,405,217 shares constitute Underwritten Shares and 210,783 shares constitute Option Shares, each as defined in the Underwriting Agreement referred to below (the “Securities”). Such registration statement, as amended as of its most recent effective date (May 30, 2019), insofar as it relates to the Securities (as determined for purposes of Rule 430B(f)(2) under the Securities Act of 1933, as amended (the “Securities Act”)), including the documents incorporated by reference therein, is herein called the “RegistrationStatement;” the related prospectus dated May 28, 2019, included in the Registration Statement filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act including the documents incorporated by reference therein, is herein called the “BaseProspectus;” the preliminary prospectus supplement dated May 28, 2019, as filed with the Commission pursuant to Rule 424(b) under the Securities Act, including the documents incorporated by reference therein, is herein called the “Preliminary Prospectus Supplement;” and the related prospectus supplement dated May 30, 2019, as filed with the Commission pursuant to Rule 424(b) under the Securities Act, including the documents incorporated by reference therein, is herein called the “Final Prospectus Supplement.” The Base Prospectus and the Preliminary Prospectus Supplement together are herein called the “Pricing Prospectus,” and the Base Prospectus and the Final Prospectus Supplement together are herein called the “FinalProspectus.”

Albany International Corp., p. 2

In arriving at the opinion expressed below, we have reviewed the following documents:

(a) an executed copy of the underwriting agreement dated May 30, 2019 (the “Underwriting Agreement”) between the Company, the Selling Stockholders and the several underwriters named in Schedule 1 thereto;

(b) the Registration Statement;

(c) the Pricing Prospectus;

(d) the Final Prospectus;

(e) a certificate of Computershare Trust Company, N.A., as registrar and transfer agent for the Securities, certifying that the Securities have been duly registered or otherwise established in the systems of The Depository Trust Company; and

(f) copies of the Company’s Amended and Restated Certificate of Incorporation and By Laws certified by the Secretary of State of the State of Delaware and the corporate secretary of the Company, respectively.

In addition, we have reviewed the originals or copies certified or otherwise identified to our satisfaction of all such corporate records of the Company and such other documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinion expressed below.

In rendering the opinion expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed (including, without limitation, the accuracy of the representations and warranties of the Selling Stockholders in the Underwriting Agreement).

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that the Securities have been validly issued by the Company and are fully paid and nonassessable.

Insofar as the foregoing opinion relates to the validity, binding effect or enforceability of any agreement or obligation of the Company, (a) we have assumed that the Company and each other party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except no such assumption is made as to the Company regarding matters of the General Corporation Law of the State of Delaware that in our experience normally would be applicable to general business entities with respect to such agreement or obligation) and (b) such opinion is subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity.

Albany International Corp., p. 3

The foregoing opinion is limited to the General Corporation Law of the State of Delaware.

We hereby consent to the filing of this opinion letter as Exhibit 5 to the Company’s Current Report on Form8-K dated June 4, 2019. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder. The opinion expressed herein is rendered on and as of the date hereof, and we assume no obligation to advise you or any other person, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinion expressed herein.

Very truly yours,
CLEARY GOTTLIEB STEEN & HAMILTON LLP
