# How to Specify NU217EM Without Mixing Nearby Parts

Look-alike part numbers are the usual way a stores ticket goes wrong on a cylindrical roller bearing for motors. Do not substitute NU314, NU215, or NU315, which remain in an older mixed title. The public Model NO. is NU217EM. Do not issue a 314 or 215 from this page. EM typically points to a machined brass cage — confirm on the inquiry.

NU217EM is listed as a cylindrical roller bearing for motors. Because a public millimetre sheet is thin on some catalog pages, confirm bore, outside diameter, and width against your drawing or the live product listing.

Review NU217EM bearing on the TFL Bearing Made-in-China listing. Shandong TFL Bearing Co., Ltd can confirm stock, packing, and any OEM marking once the drawing or sample is attached.
