The K43X48X27 RICH is a needle roller and cage assembly designed to provide a high radial load-carrying capacity in a compact form factor. This assembly does not include inner or outer rings, and its functionality relies on the hardened and precisely finished surfaces of the shaft and housing bore acting as raceways. The unit consists of 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 43 mm, an outer diameter (intended for a 48 mm housing bore), and a width of 27 mm, with an approximate weight of 0.051 kg. Manufactured in China by RICH.
