NJ318 Cylindrical roller bearing 90x190x43mm

The NJ318 is a cylindrical roller bearing with a 90mm bore diameter, 190mm outside diameter, and 43mm width. This single-row bearing 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 are commonly used in electric motors, gearboxes, machine tool spindles, and heavy industrial equipment where high radial loads and moderate speeds are present. The NJ design includes two integral ribs on the outer ring and two on the inner ring, providing axial guidance in one direction.
