This needle roller bearing carries radial loads within a compact cross-section, using full-complement needle rollers guided by a standard cage. It has no inner ring, so the shaft surface itself serves as the inner running surface, while the outer ring is fitted with 2 bords that axially locate the roller set. Outside diameter is 52.0 mm and net mass is 0.127 kg. The limiting speed reaches 11700 1/min, with a reference speed of 7100 1/min. The absence of an inner ring keeps radial space minimal and allows direct mounting on a hardened and ground shaft, which must be machined to the required tolerance to serve as the running track. The two bords on the outer ring retain the needle rollers axially, simplifying installation and handling as a single unit. With the standard cage design, the bearing suits applications where high radial load capacity is needed within limited housing space, provided speeds stay within the stated limiting and reference values.
