What is the equivalent of a 6307-2RS1 bearing?

The 6307-2RS1 is a 35×80×21mm deep groove ball bearing with verified equivalents across multiple brands: FAG 6307-2RSR, NSK 6307DDU, NTN 6307LLU, Timken 6307-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6307-2RS1 bearing?

The 6307-2RS1 bearing has a bore diameter of 35mm, outer diameter of 80mm, and width of 21mm. It has a dynamic load rating of 35.1 kN, static load rating of 19 kN, and weighs 444g. Maximum speed with grease lubrication is 12,000 rpm.

Can I replace a SKF 6307-2RS1 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 6307-2RS1 (35×80×21mm) can be replaced with the equivalent FAG part number as long as the seal type (2RS) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
