What is the equivalent of a 6211-2RS1 bearing?

The 6211-2RS1 is a 55×100×21mm deep groove ball bearing with verified equivalents across multiple brands: FAG 6211-2RSR, NSK 6211DDU, NTN 6211LLU, Timken 6211-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6211-2RS1 bearing?

The 6211-2RS1 bearing has a bore diameter of 55mm, outer diameter of 100mm, and width of 21mm. It has a dynamic load rating of 46.2 kN, static load rating of 29 kN, and weighs 591g. Maximum speed with grease lubrication is 9,000 rpm.

Can I replace a SKF 6211-2RS1 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 6211-2RS1 (55×100×21mm) can be replaced with the equivalent FAG 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.
