Provides the inner raceway for a needle roller bearing arrangement, designed as a separate cylindrical inner ring with a bore diameter of 45.0 mm and width of 22.0 mm. Net mass is 0.13 kg. The XL execution indicates an extended inner ring, allowing correct axial positioning relative to the mating needle roller and cage assembly or needle roller bearing. Because the inner ring is supplied as a separate component, it must be matched with a corresponding needle roller and cage assembly or full complement bearing sharing the same bore and width dimensions. The cylindrical bore allows mounting directly on a shaft, and the hardened raceway surface accommodates the radial loads transmitted through the needle rollers. Selection of lubrication, either grease or oil, and any additional sealing should be based on the specific needle roller bearing it is paired with.
