What is the equivalent of a 6315Z-C3 bearing?

The 6315Z-C3 is a 75×160×37mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6315ZZ C3E, NTN 6315ZZ/C3, SKF 6315-2Z C3, Timken 6315-ZZ C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6315Z-C3 bearing?

The 6315Z-C3 bearing has a bore diameter of 75mm, outer diameter of 160mm, and width of 37mm. It has a dynamic load rating of 113 kN, static load rating of 73.5 kN, and weighs 2100g. Maximum speed with grease lubrication is 4,500 rpm.

Can I replace a FAG 6315Z-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6315Z-C3 (75×160×37mm) can be replaced with the equivalent NSK part number as long as the seal type (ZZ) and clearance class (C3) match. Always verify load ratings and speed limits for your specific application.
