Rod seal for Demag AC80-1

The rod seal 604 708 40 is a specialized sealing component used in the hydraulic systems of Demag machinery. It is installed within the cylinder assembly to create a barrier between the internal fluid and the external environment, preventing leakage as the rod extends and retracts during operation. This component is specifically engineered for the Demag AC80-1 all-terrain crane, where it supports the consistent performance of lifting and stabilization functions.

This part is compatible with the Demag AC80-1 model. It is manufactured to meet the original specifications required for the hydraulic cylinders found in this equipment. By ensuring a tight fit around the cylinder rod, the seal helps maintain the necessary hydraulic pressure for the machine to perform its intended tasks effectively.

In hydraulic systems, rod seals are essential for containing fluid within the cylinder housing. They are positioned at the cylinder head to manage the dynamic movement of the rod, which is subject to constant cycling. Proper sealing prevents fluid loss, which is necessary to maintain the force and control of the hydraulic actuators throughout the crane's operation.
