Carries radial loads through a single row of needle rollers guided on an inner ring with two ribs, giving full support along the 30.0 mm width. Bore diameter is 22.0 mm, outside diameter 39.0 mm, and net mass is 144.3 g. The bearing reaches a limiting speed of 15300.0 1/min and a reference speed of 7900.0 1/min, with standard CN (Group N) radial internal clearance and a standard cage. The design has no seals, so lubricant must be supplied and retained externally, and the bearing depends on clean operating conditions or an external sealing arrangement. With CN clearance and a standard cage, it suits radial loading where the shaft and housing tolerances are controlled to keep running clearance within the intended range, without provision for axial guidance from this bearing itself.
