This needle roller bearing carries radial loads in a compact cross-section, built to DIN 617/ISO 1206 as a single-row design without an inner ring, outside diameter 45.0 mm and width 30.0 mm. Net mass is 132.0 g, the limiting speed reaches 13600 1/min, and the reference speed is 7400 1/min. The cage is of standard design. The bearing is supplied without sealing, so lubrication and contamination protection must be arranged in the housing. Since there is no inner ring, the shaft seat must be hardened and ground to serve as the raceway, allowing a slim radial envelope where full cross-section radial capacity is needed. The standard cage guides the needle rollers evenly, supporting the stated limiting and reference speed values under correct lubrication and fit conditions.
