This needle roller bearing carries axial load in a single direction, consisting of needle rollers guided in a cage without integral races, requiring flat support surfaces on the housing and shaft side to run on. The assembly has an outside diameter of 180.0 mm and a net mass of 200.0 g, built to DIN 5405-2. It is rated for a limiting speed of 1800.0 1/min and a reference speed of 710.0 1/min. The cage-guided needle arrangement gives a low axial section height for the given diameter, so it suits applications where installation space along the shaft axis is restricted. Since the design has no integral races, the mating faces must be hardened and ground to the required flatness and finish before assembly. Running direction is limited to single-direction axial loading, and lubrication as well as speed limits should be selected according to the stated limiting and reference speed values.
