This bushing fits into the threshing mechanism of a forage harvester or combine. It acts as a wear surface between a rotating shaft and its stationary housing, maintaining correct radial alignment and reducing friction on the surrounding components. As the bushing wears, clearances increase, which can lead to shaft wobble, vibration, and accelerated wear on the shaft and housing bore. The bushing is manufactured to the original dimensions so it seats correctly in the bore without requiring additional shimming. On installation, ensure the bore is clean and free of burrs.
