What is the equivalent of a 6316-2ZR bearing?

The 6316-2ZR is a 80×170×39mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6316ZZ, NTN 6316ZZ, SKF 6316-2Z, Timken 6316-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6316-2ZR bearing?

The 6316-2ZR bearing has a bore diameter of 80mm, outer diameter of 170mm, and width of 39mm. It has a dynamic load rating of 124 kN, static load rating of 80 kN, and weighs 2520g. Maximum speed with grease lubrication is 4,000 rpm.

Can I replace a FAG 6316-2ZR with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6316-2ZR (80×170×39mm) 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.
