This Teflon bushing acts as a low-friction bearing surface within the drive system of the host machine. It sits between a rotating shaft and its stationary housing, reducing wear on both components by providing a self-lubricating interface. A worn bushing allows excessive radial play, which can cause misalignment in the driven assembly and lead to accelerated wear on the shaft or housing bore. The manufacturer machines this bushing to the same inner and outer diameter tolerances as the original component, so it maintains the correct clearance without requiring shimming. On installation, ensure the bore is clean and free of burrs to avoid distorting the bushing during press-fit.
