This is a separate cylindrical inner ring designed for use with needle roller bearings that require a matching inner race. The bore diameter is 60.0 mm, width 25.0 mm, and the ring has a net mass of 0.151 kg. The XL execution indicates an extended inner ring variant, allowing correct axial positioning and support of the needle roller complement. As a separate component, it must be paired with a suitable needle roller bearing without an integral inner ring, providing a hardened running surface for the rollers. The cylindrical bore allows mounting directly on a shaft of corresponding diameter without additional adapters, and correct fit selection on the shaft ensures proper radial internal clearance during operation.
