This inner ring provides the raceway component for needle roller bearings using a separate cage and roller assembly, allowing the shaft-mounted ring to be selected independently from the outer bearing element. The cylindrical bore measures 17.0 mm, the width is 23.0 mm, and the part weighs 26.8 g net. Being a separate inner ring in the XL series, it is used where an existing needle roller and cage assembly needs a matching raceway surface with extended width, replacing a worn or missing ring rather than the full bearing. As a bare ring, it carries no seals, cage, or grease fill, so lubrication and sealing must be arranged through the mating assembly and housing design.
