# Confirming NU217EM Before the Housing Is Opened

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.

Typical duty includes electric motors and other NU-series cylindrical roller positions. Material on this listing is bearing steel. If your equipment sits outside that range, say so on the request rather than forcing a familiar part number.

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.

Review NU217EM 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.
