Dairymaster ACR ram pulley The Dairymaster ACR ram pulley is a key mechanical component in the Automatic Cluster Removal (ACR) system. It is designed to guide and support the movement of the ram mechanism, ensuring smooth and controlled operation during the attachment and removal of the milking cluster. The pulley works by helping manage the tension and alignment of any connected cables or moving parts within the ACR ram assembly. This allows for accurate response to vacuum changes and ensures the timely release of the milking cluster once milking is complete — helping to protect udder health and improve overall efficiency. Manufactured from strong, wear-resistant materials, the ACR ram pulley is built to withstand the harsh dairy environment, including exposure to moisture, cleaning agents, and mechanical stress. Replacing worn pulleys with genuine Dairymaster parts helps ensure continued reliability and system performance.
