This component provides the inner raceway for a needle roller bearing assembly, allowing separate mounting on the shaft. It is a cylindrical ring with a bore diameter of 10.0 mm and a width of 16.0 mm, with a net mass of 0.009 kg. The XL design indicates a reinforced cross-section for higher load capacity within the same envelope dimensions. Being a separate inner ring, it is fitted onto the shaft to create a hardened, precision-ground raceway surface for needle rollers, replacing the need for a hardened shaft. This allows the shaft itself to remain unhardened while still achieving the required running accuracy and surface hardness for the rolling elements.
