This needle bearing supports the rotating shafts and augers inside the header of a grain combine. It sits in the bearing housing and carries radial loads from the driven components that feed crop material into the machine. A worn bearing produces play in the supported shaft, leading to vibration and misalignment of the header drives. The manufacturer machines this bearing to the same internal clearance and race geometry as the original assembly, so it maintains the correct shaft support without requiring shimming or housing modification. On installation, ensure the bearing is pressed squarely into the housing and that the shaft rotates freely before locking the retaining hardware.
