This needle roller bearing carries radial loads through a single row of needle rollers guided by a standard cage, with bore diameter of 15.0 mm, outside diameter of 35.0 mm, and width of 20.0 mm. Net mass is 94.9 g. The limiting speed is 18500 1/min, with a reference speed of 9400 1/min, reflecting the heavy series construction of the NKIS15-XL design. Radial internal clearance falls within the CN (Group N) group, suitable for standard mounting conditions without preload requirements. The bearing has no sealing, so external lubrication and protection against contamination must be provided by the surrounding housing design. Without integrated seals, it is intended for installations where lubricant supply and sealing are handled separately, allowing direct access for grease or oil lubrication as required by the application.
