This Teflon bushing acts as a low-friction bearing surface within the drive system of a self-propelled forage harvester. It is installed at a pivot or shaft interface where it reduces metal-to-metal contact and absorbs radial loads between the rotating and stationary components. As the bushing wears, clearance in the joint increases, which can lead to vibration or misalignment of the driven assembly. The manufacturer machines this component to the original dimensional tolerances so it seats correctly in the housing without requiring additional shimming. On installation, ensure the bore and shaft are clean and free of burrs to prevent premature wear.
