Can NJ2236M be interchanged with NU2236M?

Yes, NJ2236M and NU2236M have identical dimensions (180mm x 320mm x 86mm) and are physically interchangeable. However, there is an important functional difference: NJ2236M has one flange on the inner ring for unidirectional axial location, while NU2236M has no inner ring flanges for free axial displacement. Use NJ for locating (fixed-end) positions and NU for floating-end applications where thermal expansion compensation is required.

What is the difference between NJ2236M and NJ2236EM?

Both bearings have the same dimensions (180mm x 320mm x 86mm). The difference lies in the cage design: NJ2236M features a standard machined brass cage, while NJ2236EM has an optimized machined brass cage (EM design) offering improved dynamic performance and higher load ratings (Cr: 1100kN vs 1050kN). EM series is recommended for more demanding high-speed or heavy-load applications.
