This component is a cylindrical inner ring designed to be mounted on a shaft as part of a needle roller bearing assembly, providing the running surface for the rolling elements. It has a bore diameter of 25.0 mm, a width of 26.5 mm, and a net mass of 0.043 kg. The XL designation indicates the extended width variant of the standard inner ring line. Since this is a separate inner ring rather than a complete bearing, it is intended for use with a matching needle roller and cage assembly or a full complement bearing where the shaft itself does not provide sufficient hardness or surface finish to serve as the raceway directly. The cylindrical bore allows a straightforward slide fit onto the shaft, and the ring's width must be matched to the rolling element set it is paired with for correct axial support.
