Description

This needle roller bearing supports radial loads within a compact drawn cup design, open at both ends. Outside diameter is 37.0 mm, width 12.0 mm, and net mass 22.412 g. The limiting speed reaches 8600 1/min, with a reference speed of 6600 1/min, and the bearing is supplied without sealing, manufactured to DIN 618/ISO 3245. The open-end construction allows mounting on a shaft with a hardened raceway, since the bearing itself has no inner ring. Without sealing, it requires external protection from contamination and depends on separate lubrication of the shaft raceway. The thin-wall drawn cup design minimizes radial space needed while maintaining load capacity for rotational applications within the stated speed limits.
