This needle roller bearing carries a full complement of needle rollers guided between a solid inner ring and an outer ring fitted with two ribs, giving axial location of the roller set within the outer ring. Bore diameter is 55.0 mm, outside diameter 80.0 mm, width 25.0 mm, and net mass is 406.81 g. The cage is of standard design, limiting speed is rated at 7200.0 1/min and reference speed at 4000.0 1/min. The two-rib outer ring and separate inner ring allow the bearing to take radial loads within a compact cross-section, since the needle rollers provide a high contact area relative to the bore and outside diameter. As the inner and outer rings are both present, the bearing can be mounted directly on a shaft and into a housing without an additional running surface. Lubrication and sealing are not integrated, so grease or oil supply and any sealing arrangement must be provided by the surrounding housing design.
