What is the equivalent of a 6312C3 bearing?

The 6312C3 is a 60×130×31mm deep groove ball bearing with verified equivalents across multiple brands: FAG 6312-C3, NSK 6312 C3E, NTN 6312 C3, Timken 6312 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6312C3 bearing?

The 6312C3 bearing has a bore diameter of 60mm, outer diameter of 130mm, and width of 31mm. It has a dynamic load rating of 85.2 kN, static load rating of 52 kN, and weighs 1240g. Maximum speed with grease lubrication is 7,000 rpm.

Can I replace a SKF 6312C3 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 6312C3 (60×130×31mm) 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.
