NU221-C3 Cylindrical roller bearing 105x190x36mm C3

The NU221-C3 is a single row cylindrical roller bearing with a 105mm bore diameter, 190mm outside diameter, and 36mm width. This bearing features C3 radial internal clearance, providing greater clearance than standard for applications with thermal expansion or shaft deflection.

Cylindrical roller bearings are designed for high radial load capacity and high speed operation. They are commonly used in electric motors, gearboxes, machine tool spindles, pumps, and general industrial machinery where separable construction and rigid radial support are required.
