What is the equivalent of a 120463-2 bearing?

The 120463-2 is a 50×110×27mm self-aligning ball bearing with verified equivalents across multiple brands: NSK 7310A, Timken 7310, FAG 7310-B-TVP, SKF 7310 BEP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 120463-2 bearing?

The 120463-2 bearing has a bore diameter of 50mm, outer diameter of 110mm, and width of 27mm. It has a dynamic load rating of 68.2 kN, static load rating of 47.9 kN, and weighs 1040g. Maximum speed with grease lubrication is 6,000 rpm.

Can I replace a NTN 120463-2 with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 120463-2 (50×110×27mm) 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.
