What is the equivalent of a 7218B bearing?

The 7218B is a 90×160×30mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7218A, Timken 7218, FAG 7218-B-TVP, SKF 7218 BEP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7218B bearing?

The 7218B bearing has a bore diameter of 90mm, outer diameter of 160mm, and width of 30mm. It has a dynamic load rating of 86.04 kN, static load rating of 53.6 kN, and weighs 1620g. Maximum speed with grease lubrication is 4,080 rpm.

Can I replace a NTN 7218B with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7218B (90×160×30mm) 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.
