Can NJ2860M be interchanged with NU2860M?

Yes, NJ2860M and NU2860M have identical dimensions (300mm x 380mm x 48mm) and are physically interchangeable. However, there is an important functional difference: NJ2860M has one flange on the inner ring for unidirectional axial location, while NU2860M 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.
