This self-aligning bearing assembly supports the straw walker shafts in the threshing unit of a combine harvester. It consists of two housing halves, the bearing insert, and a clamping ring that secures the assembly to the shaft. The bearing's self-aligning feature compensates for minor shaft misalignment during operation, reducing binding and wear on the walker mechanism. A worn bearing allows excessive play in the walker shaft, leading to uneven shaking and reduced separation efficiency. The manufacturer's components match the original housing geometry and clamping ring profile, ensuring the bearing seats correctly without additional shimming. When replacing, inspect the shaft surface for scoring and replace the clamping ring if deformed.
