This bearing assembly supports a rotating shaft in the header of a combine harvester or a baler pick-up. It is a sealed, ready-to-mount unit that carries radial and light axial loads from the driven components in the material feeding system. A worn bearing produces play in the supported shaft, leading to misalignment of the chain or belt drive and increased vibration. The manufacturer machines the outer race and seals to match the original housing bore, so the unit presses in without additional shimming. On replacement, inspect the housing bore for damage and clean the mounting surface before pressing the new bearing into place.
