This needle roller bearing carries radial loads within a compact cross-section, using a full complement of needle rollers guided by a standard cage running against an outside diameter of 38.0 mm. Net mass is 79.7 g, with a limiting speed of 15300 1/min and a reference speed of 8800 1/min, placing it in the light series NK29/30-XL design. The standard cage keeps the rollers evenly spaced and reduces friction compared to a full complement arrangement, supporting stable operation up to the stated reference speed under normal thermal conditions. As an open bearing without integrated sealing, it requires external protection from contamination and a separate lubrication supply, typically grease, matched to the operating speed and load. The light series construction suits applications where radial space is limited but a solid inner ring is either already present in the housing or provided separately, since NK types run directly on a shaft or a mating inner ring.
