This needle roller bearing carries the designation NKS20 and is built as a single row unit without an inner ring, with the outer ring featuring two ribs (bords) that axially locate the roller set. Outside diameter is 32.0 mm and net mass is 50.42 g. The bearing runs with a standard cage and is rated for a limiting speed of 20000 1/min, with a reference speed of 11800 1/min. The absence of an inner ring means the rollers run directly on a hardened shaft, so radial section height is kept low while radial load capacity per unit width stays high. The two ribs on the outer ring hold the roller and cage assembly in place axially, allowing the bearing to be handled and mounted as a single component before the shaft is inserted. With a standard cage design, this NKS20 unit suits applications where compact radial dimensions and direct shaft running are required, provided the mating shaft surface is hardened and ground to the necessary finish.
