NU SeriesCylindrical Roller Bearings

This page groups catalogue models carrying the NU design prefix. It is a design-family overview, not a claim that every NU designation shares one dimensional series or is interchangeable. Compare bore, outside diameter and width first, then retain the complete suffix when checking a replacement. The table shows up to 80 selected catalogue entries in ascending bore order; use the model finder for additional sizes.

Supply configuration, availability and lead time are confirmed by enquiry. Matching dimensions alone do not establish interchangeability.

SPECIFY WITH CONFIDENCE

The right dimensions. The complete designation.

Share the complete model and suffixes, required quantity, operating conditions and destination. Drawings or an original bearing reference help clarify replacement and OEM enquiries.

How to use the specification table

Start with the installation dimensions, then review the full designation, suffixes and supplied configuration. The table reads from the shared trusted model library. A dash means that no verified value is available; it does not mean zero. Application suitability still requires a review of the drawing and operating conditions.

Request a quotation from ZQM Bearings

Send the complete designation, quantity, destination, operating speed and load direction. Include photographs or drawings if the removed bearing carries additional suffixes or has special fitting and inspection requirements. Our team confirms availability and lead time for each enquiry. This table is not a live inventory listing or a guarantee of interchangeability.
