Description

This needle roller bearing carries radial loads within a compact cross-section, using a full complement of needle rollers guided by a standard cage. It is a single row design with a solid inner ring, and the outer ring features two ribs that axially locate the roller and cage assembly. Bore diameter is 50.0 mm, outside diameter 72.0 mm, width 22.0 mm, and net mass 278.0 g. The limiting speed is 7800 1/min, with a reference speed of 4150 1/min. The two-rib outer ring allows the bearing to take up axial guidance internally, simplifying housing design while keeping the roller set fixed. With a solid inner ring, the bearing can be mounted directly onto the shaft without a separate inner raceway component. The standard cage design provides even roller spacing and consistent running behavior across the stated speed range, making the bearing suitable for radial support applications where shaft space is limited and a compact section height is required.
