What is the equivalent of a NJ205E bearing?

The NJ205E is a 25×52×15mm cylindrical roller bearing with verified equivalents across multiple brands: NSK NJ205W, NTN NJ205ET2, SKF NJ 205 ECP, Timken NJ205EM. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NJ205E bearing?

The NJ205E bearing has a bore diameter of 25mm, outer diameter of 52mm, and width of 15mm. It has a dynamic load rating of 29.3 kN, static load rating of 27.7 kN, and weighs 130g. Maximum speed with grease lubrication is 10,000 rpm.

Can I replace a FAG NJ205E with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NJ205E (25×52×15mm) 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.
