Description
This needle roller bearing has a drawn outer cup with open ends, giving an outside diameter of 52.0 mm and a width of 20.0 mm, with a net mass of 55.4 g. The limiting speed is 5900 1/min and the reference speed is 4450 1/min. The bearing is manufactured to DIN 618/ISO 3245. The open-end design allows the needle roller and cage assembly to be mounted from either side, keeping radial dimensions compact for the load capacity provided by the full complement of needle rollers. As the bearing is supplied without sealing, lubrication and contamination protection must be arranged in the housing design, and axial location of the shaft must be provided separately since this bearing type accommodates only radial loads.
