Description
This needle roller bearing carries a full complement of needle rollers guided by a standard cage, with an outside diameter of 52.0 mm and a net mass of 84.7 g. It belongs to the light series, giving a compact radial cross-section for the load it carries. Limiting speed is rated at 10900 1/min, with a reference speed of 6600 1/min. The standard cage guides the needle rollers accurately and reduces friction compared to a full-complement arrangement, supporting the stated speed ratings. The bearing is designed for pure radial load and requires a separate inner ring or a hardened, ground shaft surface acting as the running surface. Lubrication and axial location of the shaft must be provided by the surrounding construction.
