POWER OF ATTORNEY

     KNOW ALL BY THESE PRESENTS, that the undersigned hereby constitutes and
appoints each of Richard D. Holder, Matthew S. Heiter, Thomas C. Burwell, Jr.,
J. Robert Atkinson, and Andrew T. Yonchak, or either of them signing singly, and
with full power of substitution, as the undersigned's true and lawful
attorney-in-fact (each, individually, an "Attorney-in-Fact" and collectively,
the "Attorneys-in-Fact") to:

  (1)    execute for and on behalf of the undersigned, in the undersigned's
capacity as a director of NN, Inc., a Delaware corporation (the "Company"),
Forms 3, 4, and 5 in accordance with Section 16(a) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act") and the rules and regulations of
the United States Securities and Exchange Commission (the "SEC") thereunder;

  (2)    do and perform any and all acts for and on behalf of the undersigned
that may be necessary or desirable to complete and execute any such Form 3, 4,
or 5, including filing and applying for and updating any accession, CCC, and CIK
filing codes (including filing SEC Form ID (or any similar form)), completing
and executing any amendment or amendments thereto, and timely filing any such
form with the SEC and any stock exchange or similar regulatory authority; and

  (3)    take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such Attorney-in-Fact, may be of benefit to,
in the best interest of, or legally required by, the undersigned, it being
understood that the documents executed by such Attorney-in-Fact on behalf of the
undersigned pursuant to this Power of Attorney shall be in such form and shall
contain such terms and conditions as such Attorney-in-Fact may approve in such
Attorney-in-Fact's discretion.

  The undersigned hereby grants to each such Attorney-in-Fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that such Attorney-in-Fact, or such
Attorney-in- Fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this Power of Attorney and the rights and powers herein
granted.  The undersigned acknowledges that the foregoing Attorneys-in-Fact, in
serving in such capacity at the request of the undersigned, are not assuming,
nor is the Company assuming, any of the undersigned's responsibilities to comply
with Section 16 of the Exchange Act.

  This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing Attorneys-in-Fact.

  This Power of Attorney revokes any currently existing power of attorney solely
to the extent any such currently existing power of attorney gives the agent(s)
designated therein the power or authority to do or perform any act or thing in
the exercise of any of the rights and powers herein granted.  This Power of
Attorney shall not be revoked by any subsequent power of attorney I may execute,
unless such subsequent power specifically refers to this Power of Attorney or
specifically states that the instrument is intended to revoke all prior powers
of attorney.

  IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 6th day of May, 2016.


                                         /s/ David K. Floyd
