This Teflon bushing acts as a low-friction bearing surface at a pivot point within the straw chopper assembly of a forage harvester. It reduces wear between the rotating and stationary components it separates, maintaining consistent alignment under load. A worn bushing allows play in the linkage, which can lead to uneven chopper operation and accelerated wear on the adjacent pivot pin. The bushing is manufactured to match the original housing bore and shaft diameter, so no additional shimming or machining is required during installation.
