Carries radial loads while keeping a compact cross-section, using a full complement of needle rollers guided by a standard cage running directly against a hardened shaft. Outside diameter is 19.0 mm and net mass is 11.68 g, with a limiting speed of 26500 1/min and a reference speed of 22400 1/min, reflecting the XL light series design. Since this needle roller bearing has no inner ring, the shaft seat must be hardened and ground to the required tolerance to serve as the raceway. The standard cage keeps the rollers evenly spaced and reduces friction, supporting operation up to the stated reference and limiting speeds, and the light series construction keeps radial space to a minimum where a slim, high-capacity radial support is needed.
