This needle roller bearing carries radial loads within a compact cross-section, designed without an inner ring to DIN 617/ISO 1206. Outside diameter is 72.0 mm, width 22.0 mm, and net mass 167.5 g. The single-row roller set runs in a standard cage, supporting a limiting speed of 7800 1/min and a reference speed of 4350 1/min. The absence of an inner ring means the shaft seat must be hardened and ground to serve as the raceway, which keeps radial section low for a given load capacity. With no seal fitted, the bearing depends on external sealing arrangements and requires clean operating conditions along with a suitable lubrication supply, typically grease or oil, applied according to the installation's needs. The standard cage design suits applications where axial guidance of the rollers is handled by the surrounding housing bore or shaft shoulder.
