What is the equivalent of a 7312A bearing?

The 7312A is a 60×130×31mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7312A, Timken 7312, FAG 7312-B-TVP, SKF 7312 BEP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7312A bearing?

The 7312A bearing has a bore diameter of 60mm, outer diameter of 130mm, and width of 31mm. It has a dynamic load rating of 73.71 kN, static load rating of 38.4 kN, and weighs 1240g. Maximum speed with grease lubrication is 4,250 rpm.

Can I replace a NTN 7312A with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7312A (60×130×31mm) 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.
