This inner ring provides the cylindrical inner raceway component designed to work together with a matching needle roller and cage assembly, completing the bearing arrangement at the shaft seat. It has a bore diameter of 38.0 mm, an overall width of 20.0 mm, and a net mass of 46.94 g, giving it the precise fit and load-carrying surface required at the shaft location. Being a separate ring, it allows the raceway to be mounted directly on the shaft while the outer housing bore accommodates the roller and cage set, simplifying disassembly and replacement without disturbing the housing fit. The cylindrical bore suits mounting on a plain shaft seat, and as a single ring component it must be paired with the corresponding roller and cage assembly matched to the same bore, width, and outside diameter dimensions.
