The K 25X30X13 is a needle roller and cage assembly designed to withstand high radial loads in applications where axial space is limited. Due to its design without inner and outer rings, the bearing requires the shaft and housing bore to act as raceways.
This configuration makes it especially suitable for compact, high-speed systems, such as gearboxes, reducers, transmissions, and motor components.
