What is the equivalent of a 7318-2RS bearing?

The 7318-2RS is a 90×190×43mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7318A-2RS, Timken 7318-2RS, FAG 7318-B-2RS-TVP, SKF 7318 BE-2RZP. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7318-2RS bearing?

The 7318-2RS bearing has a bore diameter of 90mm, outer diameter of 190mm, and width of 43mm. It has a dynamic load rating of 128.7 kN, static load rating of 80 kN, and weighs 3520g. Maximum speed with grease lubrication is 3,060 rpm.

Can I replace a NTN 7318-2RS with a NSK equivalent?

Yes. NTN and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7318-2RS (90×190×43mm) can be replaced with the equivalent NSK part number as long as the seal type (2RS) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
