Provides the inner raceway for a needle roller bearing arrangement, designed as a separate cylindrical inner ring to be mounted on the shaft. Bore diameter is 22.0 mm, width 20.0 mm, and net mass is 35.4 g, matching the corresponding needle roller and cage assembly of the XL series. Using a separate inner ring instead of running needle rollers directly on the shaft allows the shaft surface to remain unhardened, since the hardened raceway function is transferred to the ring itself. The cylindrical outer surface of the ring provides the running track for the rolling elements, and its dimensions must be matched precisely with the needle roller and cage assembly and housing bore to achieve the intended internal clearance and running accuracy.
