What is the equivalent of a 7310G bearing?

The 7310G is a 50×110×27mm angular contact ball bearing with verified equivalents across multiple brands: FAG 6310-2ZR, NSK 6310ZZ, NTN 6310ZZ, Timken 6310-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7310G bearing?

The 7310G 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 7310G with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 7310G (50×110×27mm) 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.
