This component is a cylindrical inner ring designed as a separate mounting element for needle roller bearings, providing a hardened raceway surface directly on the shaft seat. The bore diameter is 32.0 mm and the width is 30.0 mm, with a net mass of 62.4 g. Its cylindrical form allows precise fitting onto the shaft without an additional flange feature. Using a separate inner ring of this type allows the raceway to be matched independently from the shaft material and hardness, which is useful when the shaft itself cannot provide a suitable running surface for needle rollers. The IR32X37X30-XL is intended for applications where the bearing arrangement is built up from individual components, giving flexibility in axial positioning and clearance selection during assembly.
