What is the equivalent of a 7211A bearing?

The 7211A is a 55×100×21mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7211A, Timken 7211, FAG 7211-B-TVP, SKF 7211 BEP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7211A bearing?

The 7211A bearing has a bore diameter of 55mm, outer diameter of 100mm, and width of 21mm. It has a dynamic load rating of 46.3 kN, static load rating of 36 kN, and weighs 598g. Maximum speed with grease lubrication is 6,100 rpm.

Can I replace a NTN 7211A with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7211A (55×100×21mm) 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.
