Carries axial loads in one direction through a single row of needle rollers guided in a cage, transmitting force directly between two flat bearing washers or housing faces without an inner or outer ring. Outside diameter is 70.0 mm, net mass 19.5 g, limiting speed 4800.0 1/min and reference speed 1950.0 1/min, built to DIN 5405-2 as an axial needle roller and cage assembly. Because it consists only of rollers and cage, this needle roller bearing requires hardened and ground shaft and housing seating surfaces to act as raceways, and axial clearance must be set through the surrounding construction. Its low cage mass keeps operating temperature moderate at speeds up to the reference value, while the compact axial section suits arrangements where radial space along the shaft axis is limited. Lubrication and sealing are provided externally, matched to the counterface design in the assembly.
