Provides the cylindrical bore surface for a needle roller bearing assembly, serving as the mating inner race where a separate outer ring or housing bore is used. Bore diameter is 65.0 mm, width is 35.0 mm, and net mass is 0.237 kg. The XL designation indicates extended inner ring dimensions matched to the corresponding needle roller and cage assembly. Being a separate inner ring, it allows the raceway to be replaced independently of the surrounding bearing components and supports mounting configurations where the shaft itself does not serve as the running surface. Correct fit and alignment with the matched needle roller and cage assembly are required to maintain proper radial internal clearance and running accuracy.
