What is the equivalent of a NJ219EM bearing?

The NJ219EM is a 45×85×19mm cylindrical roller bearing with verified equivalents across multiple brands: NSK NJ209W, NTN NJ209ET2, SKF NJ 209 ECP, Timken NJ209EM. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NJ219EM bearing?

The NJ219EM bearing has a bore diameter of 45mm, outer diameter of 85mm, and width of 19mm. It has a dynamic load rating of 46 kN, static load rating of 47 kN, and weighs 430g. Maximum speed with grease lubrication is 6,000 rpm.

Can I replace a FAG NJ219EM with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NJ219EM (45×85×19mm) 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.

NJ219EM

OpenCNCylindrical Roller BearingCylindrical Roller — Light Series (NJ)

Single row cylindrical roller bearings with ribs on the outer ring and one rib on the inner ring. NJ-type provides axial restraint in one direction, suitable as a semi-locating bearing. Same dimensions as NU200 series.
