This reinforced metal-rubber bushing mounts in the sieve assembly of a combine harvester, where it acts as a pivot or support point for moving components within the cleaning unit. It absorbs vibration and reduces metal-to-metal contact between the sieve frame and its linkage, helping maintain consistent sieve oscillation. A worn bushing introduces play in the linkage, which can cause uneven sieve movement and reduce cleaning efficiency. The bushing is manufactured to match the original assembly's outer diameter and height so it seats fully in the housing without shimming. On installation, ensure the bore is clean and free of debris before pressing the bushing into place.
