This needle roller bearing carries radial loads while keeping a compact cross-section, using a full complement of needle rollers guided in a standard cage. The outside diameter is 57.0 mm and net mass is 0.143 kg, with a limiting speed of 9800 1/min and a reference speed of 5800 1/min, corresponding to the light NK47/30-XL series. The standard cage guides the needle rollers and maintains even load distribution across the roller set, supporting the rated speed values without additional flange components. Its slim outer diameter relative to load capacity makes it suited for radial support where shaft space is limited and where a separate inner ring or shaft surface is machined to serve as the running surface.
