Description

This needle roller bearing uses a drawn cup design with an open end, built to DIN 618, with an outside diameter of 47.0 mm and a net mass of 47.66 g. Sealing is provided on both sides by lip seals (2RS), and the bearing is rated for a limiting speed of 3950 1/min. The thin-walled drawn cup construction keeps radial space requirements low while the full complement of needle rollers gives high radial load capacity for the given envelope. The double lip seal arrangement protects the rolling elements from contamination and retains grease inside the cup, making the bearing suitable for applications where sealing against dirt and moisture ingress matters more than precise axial guidance, since the open-end design does not locate the shaft axially.
