This ball bearing supports the rotating shaft inside the grain-tank unloading system of a combine harvester. It carries radial and light axial loads from the auger or conveyor assembly that moves grain toward the discharge spout. The 2RS contact seals on both sides retain factory grease and block dust, chaff, and moisture from entering the raceway. A worn bearing produces rumble or shaft wobble, which can misalign the auger and reduce unloading speed. SKF manufactures this bearing to the same internal clearance and seal geometry as the original component, so it seats in the housing without shimming and maintains the correct shaft alignment. Replace the bearing as a set with the adjacent seal if the housing bore shows wear.
