NU228 Cylindrical roller bearing 140x250x42mm

The NU228 is a cylindrical roller bearing with a 140mm bore diameter, 250mm outside diameter, and 42mm width. This single-row design features high radial load capacity and allows axial displacement of the shaft relative to the housing, accommodating thermal expansion in machinery.

Cylindrical roller bearings of this size are commonly used in heavy industrial applications including electric motors, gearboxes, industrial pumps, and machine tool spindles where high radial loads and moderate speeds are present. The separable design facilitates mounting and maintenance procedures.
