What is the equivalent of a 7306 bearing?

The 7306 is a 30×72×19mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7306A, Timken 7306, FAG 7306-B-TVP, SKF 7306 BEP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7306 bearing?

The 7306 bearing has a bore diameter of 30mm, outer diameter of 72mm, and width of 19mm. It has a dynamic load rating of 31 kN, static load rating of 19.3 kN, and weighs 331g. Maximum speed with grease lubrication is 9,600 rpm.

Can I replace a NTN 7306 with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7306 (30×72×19mm) 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.
