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.
