This ball bearing supports rotating shafts in the threshing mechanism drive and the water pump of the host machine. It is a single-row, deep-groove design with rubber seals on both sides, which retain lubricant and exclude contaminants. The bearing carries radial and moderate axial loads, maintaining alignment between the shaft and housing under normal operating speeds. A worn bearing produces audible rumble or vibration, and if left unchecked can cause shaft misalignment that damages the housing bore or the driven component. As an original-manufacturer part, the seal geometry matches the housing counterbore depth, so the seal lip contacts the shaft race at the correct interference without requiring additional shimming. On installation, press the bearing onto the shaft using the inner ring face only; do not apply force through the outer ring.
