What is the equivalent of a 6310C3 bearing?

The 6310C3 is a 50×110×27mm deep groove ball bearing with verified equivalents across multiple brands: FAG 6310-C3, NSK 6310 C3E, NTN 6310 C3, Timken 6310 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6310C3 bearing?

The 6310C3 bearing has a bore diameter of 50mm, outer diameter of 110mm, and width of 27mm. It has a dynamic load rating of 65 kN, static load rating of 38 kN, and weighs 1070g. Maximum speed with grease lubrication is 8,500 rpm.

Can I replace a SKF 6310C3 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 6310C3 (50×110×27mm) 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.
