What is the equivalent of a 631785 bearing?

The 631785 is a 60×110×22mm deep groove ball bearing with verified equivalents across multiple brands: FAG 6212-C3, NSK 6212 C3E, NTN 6212 C3, Timken 6212 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 631785 bearing?

The 631785 bearing has a bore diameter of 60mm, outer diameter of 110mm, and width of 22mm. It has a dynamic load rating of 55.3 kN, static load rating of 36 kN, and weighs 755g. Maximum speed with grease lubrication is 8,000 rpm.

Can I replace a SKF 631785 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 631785 (60×110×22mm) can be replaced with the equivalent FAG part number as long as the seal type (open) and clearance class (C3) match. Always verify load ratings and speed limits for your specific application.
