The K38X43X27 RICH is a needle roller and cage assembly designed to provide a high radial load capacity within a compact design. This assembly does not include inner or outer rings, and its performance depends on the hardened and precisely finished surfaces of the shaft and housing bore serving as the raceways. It comprises a set of needle rollers accurately positioned and guided by a steel cage, ensuring smooth and efficient rolling motion. The dimensions indicate a nominal bore diameter (for the shaft raceway) of 38 mm, an outer diameter (intended for a 43 mm housing bore), and a width of 27 mm, with an approximate weight of 0.038 kg. Manufactured in China by RICH.
