What is the equivalent of a 1218F bearing?

The 1218F is a 90×160×30mm self-aligning ball bearing with verified equivalents across multiple brands: NSK 6218ZZ, NTN 6218ZZ, SKF 6218-2Z, Timken 6218-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 1218F bearing?

The 1218F 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 1218F with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 1218F (90×160×30mm) 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.
