What is the equivalent of a NU307ET2 bearing?

The NU307ET2 is a 35×80×21mm cylindrical roller bearing with verified equivalents across multiple brands: NSK NU307W, NTN NU307ET2, SKF NU 307 ECP, Timken NU307EM. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NU307ET2 bearing?

The NU307ET2 bearing has a bore diameter of 35mm, outer diameter of 80mm, and width of 21mm. It has a dynamic load rating of 49.5 kN, static load rating of 47 kN, and weighs 460g. Maximum speed with grease lubrication is 6,700 rpm.

Can I replace a FAG NU307ET2 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NU307ET2 (35×80×21mm) 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.
