What is the equivalent of a 7220BMB bearing?

The 7220BMB is a 100×180×34mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7220A, Timken 7220, FAG 7220-B-TVP, SKF 7220 BEP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7220BMB bearing?

The 7220BMB bearing has a bore diameter of 100mm, outer diameter of 180mm, and width of 34mm. It has a dynamic load rating of 112.5 kN, static load rating of 74.4 kN, and weighs 2360g. Maximum speed with grease lubrication is 3,400 rpm.

Can I replace a NTN 7220BMB with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7220BMB (100×180×34mm) 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.
