What is the equivalent of a 7304-B-TVP bearing?

The 7304-B-TVP is a 20×52×15mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7304A, Timken 7304, FAG 7304-B-TVP, SKF 7304 BEP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7304-B-TVP bearing?

The 7304-B-TVP bearing has a bore diameter of 20mm, outer diameter of 52mm, and width of 15mm. It has a dynamic load rating of 14.31 kN, static load rating of 6.24 kN, and weighs 89g. Maximum speed with grease lubrication is 11,900 rpm.

Can I replace a NTN 7304-B-TVP with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7304-B-TVP (20×52×15mm) can be replaced with the equivalent NSK part number as long as the seal type (open) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
