This bearing is a component of the threshing mechanism in a combine harvester or self-propelled forage harvester. It supports a rotating shaft within the threshing drum or rotor assembly, maintaining alignment under load. A worn bearing introduces radial play, which leads to vibration, misalignment of the threshing elements, and reduced separation efficiency. As an original-manufacturer part, the bearing is produced to the same internal clearance and raceway geometry as the component it replaces, so no shimming or housing modification is required during installation.
