What is the equivalent of a 217-SFF bearing?

The 217-SFF is a 85×150×28mm ball bearing with verified equivalents across multiple brands: NSK 6217DDU, NTN 6217LLU, SKF 6217-2RS1, Timken 6217-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 217-SFF bearing?

The 217-SFF bearing has a bore diameter of 85mm, outer diameter of 150mm, and width of 28mm. It has a dynamic load rating of 83.2 kN, static load rating of 57 kN, and weighs 1280g. Maximum speed with grease lubrication is 5,000 rpm.

Can I replace a FAG 217-SFF with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 217-SFF (85×150×28mm) can be replaced with the equivalent NSK part number as long as the seal type (2RS) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
