This chain link connects two ends of a roller chain, forming a continuous loop that transmits drive power within the forage harvester's feed or conveying system. It sits between the pin and roller assemblies of the adjacent chain sections, maintaining the correct pitch and alignment under load. A worn or stretched link causes uneven chain tension, leading to sprocket wear and potential chain jump. This original component is formed to the same pin diameter and roller width as the factory chain, so it seats correctly without forcing the side plates.
