This Teflon bushing acts as a low-friction bearing surface inside the grain tank unloading system. It supports a rotating shaft or linkage, reducing wear between moving metal parts during the auger or conveyor cycle. A worn bushing allows play in the linkage, which can cause misalignment and binding of the unloading mechanism. The bushing is made from a self-lubricating material that does not require additional grease, simplifying maintenance. On installation, ensure the bore is clean and free of debris so the bushing seats fully against its housing shoulder.
