This needle roller bearing carries the full complement of rollers guided by a standard cage, with an outside diameter of 72.0 mm and a net mass of 0.259 kg. The XL designation indicates a modified internal design compared to the standard NK series. Limiting speed is rated at 7700 1/min, with a reference speed of 4800 1/min. The standard cage guides the rollers and maintains proper spacing, supporting operation up to the stated limiting speed. Due to the absence of an inner ring, this bearing requires a hardened and ground shaft surface to serve as the raceway, making it suitable for applications where radial space is limited and a separate inner ring is not required. The rated speed values indicate the thermal and mechanical limits under which the bearing can be operated reliably.
