What is the equivalent of a 6218C3 bearing?

The 6218C3 is a 90×160×30mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6218 C3E, NTN 6218 C3, SKF 6218 C3, Timken 6218 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6218C3 bearing?

The 6218C3 bearing has a bore diameter of 90mm, outer diameter of 160mm, and width of 30mm. It has a dynamic load rating of 95.6 kN, static load rating of 67 kN, and weighs 1620g. Maximum speed with grease lubrication is 4,800 rpm.

Can I replace a FAG 6218C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6218C3 (90×160×30mm) can be replaced with the equivalent NSK part number as long as the seal type (open) and clearance class (C3) match. Always verify load ratings and speed limits for your specific application.
