The K47X52X27 RICH is a needle roller and cage assembly designed for applications requiring high radial load capacity within a compact space. This assembly does not include inner or outer rings, and its performance is directly dependent on the hardness and surface finish of the shaft and housing bore serving as the raceways. The assembly consists of precisely arranged needle rollers held by a steel cage, which ensures optimal roller guidance and spacing, leading to smooth and efficient operation. The dimensions indicate a nominal bore diameter (for the shaft raceway) of 47 mm, an outer diameter (fitting into a 52 mm housing bore), and a width of 27 mm, with an approximate weight of 0.055 kg. Manufactured in China by RICH.
