NU321-C3 Cylindrical roller bearing 105x225x49mm C3

The NU321-C3 is a single row cylindrical roller bearing with a 105mm bore diameter, 225mm outside diameter, and 49mm width. This bearing features C3 radial internal clearance, providing greater clearance than standard to accommodate thermal expansion or shaft deflection in operating conditions.

Cylindrical roller bearings are designed for high radial load capacity and are commonly used in electric motors, gearboxes, machine tool spindles, and other industrial applications requiring precise radial guidance and high rotational speeds. The separable design allows for simplified mounting and dismounting.
