The NJ309 is a single-row cylindrical roller bearing with dimensions of 45mm bore, 100mm outside diameter, and 25mm width. This bearing design features high radial load capacity and allows axial displacement of the shaft relative to the housing, making it suitable for applications requiring accommodation of thermal expansion.
Cylindrical roller bearings are commonly used in electric motors, gearboxes, machine tool spindles, and industrial pumps where high radial loads and moderate speeds are present. The NJ design includes inner ring ribs on both sides and an outer ring rib on one side, providing axial guidance in one direction.
