This needle roller bearing carries a solid outer ring with machined guide ribs, giving a full complement of needle rollers direct contact against the shaft, which must serve as the inner raceway. Outside diameter is 24.0 mm, net mass 27.4 g, limiting speed reaches 23200 1/min, and reference speed is 15900 1/min. Cage execution is standard. The absence of an inner ring keeps radial section low while allowing high radial load capacity within the available envelope. Standard cage design guides the needle rollers evenly around the raceway, supporting stable operation up to the stated limiting speed. As the design relies on a hardened and ground shaft surface for the running track, correct shaft tolerance and surface finish are required to achieve proper rolling contact and expected service life.
