This needle roller bearing carries radial loads without an inner ring, following the DIN 617/ISO 1206 design of the RNA series. The outside diameter is 80.0 mm and net mass is 485.0 g. It is built with a standard cage and two rows of rollers (ZW), giving increased radial load capacity within the same envelope compared to a single-row design. The limiting speed is rated at 7200 1/min, with a reference speed of 4200 1/min. The bearing has no sealing, so it depends on external sealing and clean lubrication conditions at the mounting location. The absence of an inner ring means the shaft seat must be hardened and ground to serve as the raceway, and the standard cage guides the rollers to maintain even load distribution across the double row. This construction suits applications where radial space is limited but full utilization of the available diameter for load capacity is required, provided that lubrication and sealing are supplied by the surrounding housing design.
