Carries radial loads within a compact cross-section thanks to a full complement of needle rollers running directly against the shaft, since this design has no inner ring. The outside diameter is 16.0 mm and the net mass is 9.67 g, so the bearing fits into tight housing spaces. The TV cage, made of pressed steel, guides the needle rollers and keeps them evenly spaced during rotation. The limiting speed reaches 31000 1/min, with a reference speed of 32000 1/min. Being a needle roller bearing without an inner ring, it requires a hardened and ground shaft seat to serve as the running surface for the rollers. The TV cage keeps friction and mass low, supporting the high permissible speed values, while the light NK series construction suits applications where radial space is limited and a separate inner ring is not needed. Lubrication should be applied according to the operating speed and load to maintain the running surface between rollers and shaft.
