What is the equivalent of a 60122 bearing?

The 60122 is a 40×90×23mm deep groove ball bearing with verified equivalents across multiple brands: FAG 6308, NSK 6308, NTN 6308, Timken 6308. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 60122 bearing?

The 60122 bearing has a bore diameter of 40mm, outer diameter of 90mm, and width of 23mm. It has a dynamic load rating of 42.3 kN, static load rating of 24 kN, and weighs 611g. Maximum speed with grease lubrication is 11,000 rpm.

Can I replace a SKF 60122 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 60122 (40×90×23mm) can be replaced with the equivalent FAG 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.
