What is the equivalent of a 7210A bearing?

The 7210A is a 50×90×20mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7210A, Timken 7210, FAG 7210-B-TVP, SKF 7210 BEP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7210A bearing?

The 7210A bearing has a bore diameter of 50mm, outer diameter of 90mm, and width of 20mm. It has a dynamic load rating of 37.4 kN, static load rating of 28.6 kN, and weighs 453g. Maximum speed with grease lubrication is 6,700 rpm.

Can I replace a NTN 7210A with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7210A (50×90×20mm) 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.
