What is the equivalent of a 1310 bearing?

The 1310 is a 50×108×23mm self-aligning ball bearing with verified equivalents across multiple brands: FAG 1310-TVH, NSK 1310, NTN 1310, Timken 1310. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 1310 bearing?

The 1310 bearing has a bore diameter of 50mm, outer diameter of 108mm, and width of 23mm. It has a dynamic load rating of 29.8 kN, static load rating of 15.1 kN, and weighs 623g. Maximum speed with grease lubrication is 5,355 rpm.

Can I replace a SKF 1310 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 1310 (50×108×23mm) 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.
