This inner ring is designed to be used together with a matching needle roller bearing assembly, providing the cylindrical inner running surface for the rolling elements. It has a bore diameter of 90.0 mm, a width of 35.0 mm and a net mass of 0.615 kg, giving it a solid, rigid cross-section suitable for the load path of the mating outer components. Being supplied as a separate inner ring, it allows the bearing arrangement to be assembled and dismantled independently of the shaft fit, which simplifies mounting and replacement when the ring surface becomes worn. As a bare ring without integrated sealing or lubrication, it requires the lubricant and sealing solution to be provided by the surrounding housing design, and its cylindrical bore is intended for a straightforward interference or locational fit on the shaft.
