What is the equivalent of a NJ316ECP bearing?

The NJ316ECP is a 30×72×19mm cylindrical roller bearing with verified equivalents across multiple brands: NSK NJ306W, NTN NJ306ET2, SKF NJ 306 ECP, Timken NJ306EM. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NJ316ECP bearing?

The NJ316ECP bearing has a bore diameter of 30mm, outer diameter of 72mm, and width of 19mm. It has a dynamic load rating of 53 kN, static load rating of 50 kN, and weighs 398g. Maximum speed with grease lubrication is 7,500 rpm.

Can I replace a FAG NJ316ECP with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NJ316ECP (30×72×19mm) 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.
