The K 75x83x30 RICH is a needle roller and cage assembly engineered for applications demanding high radial load capacity within a confined space. This assembly does not include inner or outer rings, relying on the precision and hardness of the shaft and housing bore to serve as the bearing raceways. It comprises a carefully selected set of needle rollers retained and guided by a steel cage, which ensures optimal roller spacing and movement, contributing to smooth and efficient operation. The dimensions indicate a nominal bore diameter (for the shaft raceway) of 75 mm, an outer diameter (intended to fit into an 83 mm housing bore), and a width of 30 mm, with an approximate weight of 0.144 kg. Manufactured in China by RICH.
