What is the equivalent of a 6317ZZ bearing?

The 6317ZZ is a 85×180×41mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6317ZZ, NTN 6317ZZ, SKF 6317-2Z, Timken 6317-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6317ZZ bearing?

The 6317ZZ bearing has a bore diameter of 85mm, outer diameter of 180mm, and width of 41mm. It has a dynamic load rating of 133 kN, static load rating of 90 kN, and weighs 3000g. Maximum speed with grease lubrication is 3,800 rpm.

Can I replace a FAG 6317ZZ with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6317ZZ (85×180×41mm) can be replaced with the equivalent NSK part number as long as the seal type (ZZ) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
