The NJ308-C4 is a single-row cylindrical roller bearing with a 40mm bore diameter, 90mm outside diameter, and 23mm width. This NJ-type bearing features a two-rib outer ring design with one rib on the inner ring, allowing axial displacement of the shaft relative to the housing. The C4 designation indicates a radial internal clearance greater than C3, suitable for applications with thermal expansion or shaft deflection.
Cylindrical roller bearings are commonly used in electric motors, gearboxes, pumps, compressors, and machine tool spindles where high radial load capacity and moderate speeds are required. The separable design facilitates mounting and dismounting, while the roller-raceway contact provides excellent load distribution for heavy-duty industrial applications.
