Overview

NSK NU221WC3 Cylindrical Roller Bearing is designed for high radial load capacity through line contact between rollers and raceways. It is suitable for rigid, heavy-duty applications such as motors, gearboxes, rolling mills, and machine tools, with N, NU, NJ, and NUP designs offering different axial locating functions.

Cylindrical rollers and a cage are arranged between inner and outer ring raceways. Depending on flange configuration, the bearing can be separable and may support axial load in one or both directions.
