This Teflon bushing serves as a wear-surface liner in the drive system of a self-propelled forage harvester. It fits between rotating and stationary components, reducing friction and maintaining alignment under load. The bushing material provides a low-friction interface that resists galling, which is critical in a high-torque driveline where metal-to-metal contact would accelerate wear. A worn bushing allows play in the drive train, leading to misalignment and increased vibration. The part is machined to match the original housing bore and shaft diameter, so no additional shimming is required during installation.
