NJ319-C4 is a cylindrical roller bearing, 95 mm bore × 200 mm OD × 45 mm wide (3.7402 × 7.874 × 1.7717 in). It has C4 internal clearance.
The NJ319-C4 is a cylindrical roller bearing with a 95mm bore diameter, 200mm outside diameter, and 45mm width. This single-row bearing features the NJ design with a removable inner ring and integral flanges on the outer ring, providing radial load capacity with axial guidance in one direction. The C4 radial clearance specification provides greater internal clearance than standard, suited for applications with thermal expansion or shaft deflection.
