This inner ring provides the raceway for a needle roller bearing set up as a separate inner ring component, allowing the bearing arrangement to be assembled with a matched outer element and rolling elements chosen independently. The cylindrical bore measures 95.0 mm, the ring width is 63.0 mm, and the net mass is 1.172 kg, corresponding to the XL execution of the IR series. Because the inner ring is supplied as a separate part, it allows the shaft seat to be finished to the required tolerance independently of the housing bore, giving flexibility in achieving the intended internal clearance of the complete bearing. The cylindrical bore design permits a simple slide fit onto the shaft, and the component can be paired with a matching outer ring and roller/cage assembly of corresponding dimensions to complete the bearing arrangement.
