What is the equivalent of a NJ211ET2 bearing?

The NJ211ET2 is a 55×100×21mm cylindrical roller bearing with verified equivalents across multiple brands: NSK NJ211W, NTN NJ211ET2, SKF NJ 211 ECP, Timken NJ211EM. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NJ211ET2 bearing?

The NJ211ET2 bearing has a bore diameter of 55mm, outer diameter of 100mm, and width of 21mm. It has a dynamic load rating of 58 kN, static load rating of 62.5 kN, and weighs 636g. Maximum speed with grease lubrication is 5,000 rpm.

Can I replace a FAG NJ211ET2 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NJ211ET2 (55×100×21mm) can be replaced with the equivalent NSK part number as long as the seal type (open) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
