This needle roller bearing carries axial loads in one direction only, built as a cage assembly with needle rollers positioned by a thin cage, without integrated washers. Outside diameter is 145.0 mm, net mass 106.0 g, limiting speed reaches 2260 1/min, with a reference speed of 890 1/min. The design follows DIN 5405-2. Because the assembly consists of rollers and cage alone, it requires flat hardened bearing and housing washer surfaces machined into the surrounding construction to form the running tracks. This makes the axial section low, suiting applications where installation space along the shaft axis is limited. The open cage design requires the operator to provide lubrication and sealing arrangements, matching the running clearance and precision class to the surrounding construction rather than relying on any built-in provision.
