What is the equivalent of a 121.76.01-24 bearing?

The 121.76.01-24 is a 75×130×25mm ball bearing with verified equivalents across multiple brands: NSK 6215, NTN 6215, SKF 6215, Timken 6215. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 121.76.01-24 bearing?

The 121.76.01-24 bearing has a bore diameter of 75mm, outer diameter of 130mm, and width of 25mm. It has a dynamic load rating of 61.8 kN, static load rating of 41.5 kN, and weighs 810g. Maximum speed with grease lubrication is 6,000 rpm.

Can I replace a FAG 121.76.01-24 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 121.76.01-24 (75×130×25mm) can be replaced with the equivalent NSK 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.
