This needle roller bearing carries a solid inner ring, giving it a bore diameter of 15.0 mm, an outside diameter of 27.0 mm and a width of 20.0 mm, with a net mass of 49.4 g. It reaches a limiting speed of 21600 1/min and a reference speed of 12100 1/min, and is fitted with a standard cage and CN (Group N) radial internal clearance. The solid inner ring allows direct mounting on the shaft, providing full support along the roller path and stable radial guidance. The CN clearance and standard cage suit continuous radial-load operation within the stated speed range, while the compact cross-section of the light series keeps the radial envelope small for a given bore size.
