This tapered roller bearing supports the shaft in the grain unloading drive of a self-propelled forage harvester. It carries combined radial and axial loads from the drive system, maintaining alignment between the rotating shaft and its housing. A worn bearing produces audible rumble and shaft play, which can lead to misalignment and accelerated wear of the mating gears or sprockets. Bepco manufactures this component to match the original bearing's internal geometry, so it seats correctly in the housing without shimming. On installation, press the bearing onto the shaft and into the housing bore, then verify that the retaining hardware is torqued to specification.
