What is the equivalent of a 620212 bearing?

The 620212 is a 45×100×25mm deep groove ball bearing with verified equivalents across multiple brands: NSK NJ309W, NTN NJ309ET2, SKF NJ 309 ECP, Timken NJ309EM. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 620212 bearing?

The 620212 bearing has a bore diameter of 45mm, outer diameter of 100mm, and width of 25mm. It has a dynamic load rating of 74 kN, static load rating of 71 kN, and weighs 856g. Maximum speed with grease lubrication is 5,300 rpm.

Can I replace a FAG 620212 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 620212 (45×100×25mm) 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.
