This inner ring is designed to be used as a separate raceway component paired with a needle roller and cage assembly, forming a complete bearing arrangement where the inner ring is not integrated into the roller unit. It has a cylindrical bore of 38.0 mm, a width of 30.0 mm, and a net mass of 73.2 g. The cylindrical form allows a straightforward fit onto a shaft without additional axial features on the bore surface. Since the component supplies the inner raceway surface only, its running accuracy and surface finish directly affect the load path of the needle rollers running on it. It should be mounted with the shaft tolerance appropriate for the fit class required by the mating roller and cage assembly, and shaft hardness and surface finish at the contact area should match the raceway requirements to ensure correct rolling contact.
