What is the equivalent of a 88501 bearing?

The 88501 is a 12×37×12mm ball bearing with verified equivalents across multiple brands: SKF 6301-2RS1, NSK 6301DDU, NTN 6301LLU, Timken 6301-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 88501 bearing?

The 88501 bearing has a bore diameter of 12mm, outer diameter of 37mm, and width of 12mm. It has a dynamic load rating of 10.1 kN, static load rating of 4.15 kN, and weighs 57.4g. Maximum speed with grease lubrication is 28,000 rpm.

Can I replace a FAG 88501 with a SKF equivalent?

Yes. FAG and SKF bearings with the same ISO designation are dimensionally interchangeable. The 88501 (12×37×12mm) can be replaced with the equivalent SKF 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.
