What to confirm before choosing Cylindrical Roller Bearings

Check NU/NJ/NUP configurations and axial location requirements before specifying a series.

Radial load, speed, operating cycle and temperature.

Axial movement

Fixed-end or free-end design and thermal movement allowance.

Common questions

What is the practical difference between NU and NJ?

The rib arrangement changes how axial guidance is handled; verify the full mounting arrangement.
