This component provides the inner raceway for a needle roller bearing arrangement, supplied as a separate cylindrical inner ring designated IR35X40X17-XL. The bore diameter is 35.0 mm, width is 17.0 mm, and net mass is 38.0 g, giving an outer seat diameter of 40.0 mm for the mating needle roller and cage assembly. Being a separate ring, IR35X40X17-XL allows the bearing arrangement to be assembled onto the shaft independently of the outer bearing components, which is useful when a hardened and ground raceway surface is required directly on the shaft seat. The cylindrical design (XL suffix) indicates an extended series ring suited to full-complement or caged needle roller sets sharing the same bore and width dimensions.
