What is the equivalent of a NU-208-ECP-C3 bearing?

The NU-208-ECP-C3 is a 40×80×18mm ball bearing with verified equivalents across multiple brands: NSK NU208W C3, NTN NU208ET2 C3, SKF NU 208 ECP/C3, Timken NU208EM/C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NU-208-ECP-C3 bearing?

The NU-208-ECP-C3 bearing has a bore diameter of 40mm, outer diameter of 80mm, and width of 18mm. It has a dynamic load rating of 43.5 kN, static load rating of 43 kN, and weighs 375g. Maximum speed with grease lubrication is 6,700 rpm.

Can I replace a FAG NU-208-ECP-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NU-208-ECP-C3 (40×80×18mm) can be replaced with the equivalent NSK part number as long as the seal type (open) and clearance class (C3) match. Always verify load ratings and speed limits for your specific application.
