The upper auger bushing is a wear-resistant component that supports the auger shaft near the top of the housing in pellet or biomass burners. It reduces friction and maintains proper alignment, ensuring smooth rotation and consistent fuel feed. Over time, bushings can wear out, leading to noise or inefficient operation. Replacing the upper auger bushing as part of routine maintenance helps prolong the life of your burner system.
