This separate cylindrical inner ring is designed for needle roller bearings that require a matched inner raceway, allowing the bore fit to be set independently from the outer bearing assembly. It has a bore diameter of 130.0 mm and a width of 35.0 mm, with a net mass of 850.0 g. The XL execution provides a heavy-duty cross-section suited to the load-bearing raceway surface for the corresponding roller and cage assembly. Because the inner ring is supplied as a separate component, it allows selection of the fit and axial positioning to match the shaft design during assembly. The cylindrical bore permits mounting directly onto a plain shaft seat, with the raceway hardened to withstand rolling contact loads corresponding to the specified bore and width dimensions. No integral flange or sealing elements are included, so shaft location and lubrication must be provided by the surrounding housing design.
