Description
This combined needle roller bearing carries radial load through its needle roller set and axial load in one direction through an integrated axial ball bearing, following DIN 5429. Bore diameter is 40.0 mm, outside diameter 52.0 mm, height 32.0 mm, net mass 207.57 g, and limiting speed reaches 4000.0 1/min. It uses a standard cage and has no end cap. The design suits applications where radial and one-directional axial load must be supported at a single mounting point without adding a separate thrust bearing, saving axial space. As it has no seal, the bearing requires external protection from contamination and must be lubricated with oil rather than grease. The absence of an end cap means axial location and load path on the ball bearing side need to be secured by the surrounding housing design.
