What is the equivalent of a 6210ZZ bearing?

The 6210ZZ is a 50×90×20mm deep groove ball bearing with verified equivalents across multiple brands: FAG 6210-2ZR, NSK 6210ZZ, NTN 6210ZZ, Timken 6210-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6210ZZ bearing?

The 6210ZZ bearing has a bore diameter of 50mm, outer diameter of 90mm, and width of 20mm. It has a dynamic load rating of 37.1 kN, static load rating of 23.2 kN, and weighs 442g. Maximum speed with grease lubrication is 10,000 rpm.

Can I replace a SKF 6210ZZ with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 6210ZZ (50×90×20mm) can be replaced with the equivalent FAG part number as long as the seal type (ZZ) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
