Carries radial loads within a compact cross-section, using a full complement of needle rollers guided by a standard cage in a single row. Outside diameter is 55.0 mm, width 20.0 mm, and net mass 0.109 kg. Limiting speed reaches 10700 1/min, with a reference speed of 6100 1/min. This needle roller bearing has no seals, so mounting must ensure external protection against contamination, and lubrication with grease or oil is applied through the housing. The standard cage design keeps the rollers evenly spaced, supporting stable running at the rated speeds. As a separable bearing without an inner ring, it requires a matching shaft raceway or inner ring for correct radial guidance and load distribution.
