Carries radial loads within a compact outer diameter of 17.0 mm, using a full complement of needle rollers guided by a TV cage for stable roller spacing and reduced friction. The design has no inner ring, so the bearing runs directly on a hardened and ground shaft. Net mass is 13.6 g, and the bearing is rated for a limiting speed of 29500 1/min and a reference speed of 28500 1/min, reflecting the light NK series construction. The TV cage design keeps roller pitch consistent under load and supports smooth operation at the stated speed range. Because there is no inner ring, radial section height stays low, which suits applications where shaft space is restricted and a hardened shaft surface can serve as the raceway. The XL designation indicates the bearing has an increased load rating compared to the standard version of the same envelope dimensions, allowing higher radial loads to be carried within the same outer diameter of 17.0 mm.
