The Glydring, part number 604 709 40, serves as a specialized sealing element for the hydraulic systems of the Demag AC80-1 crane. It is engineered to maintain a tight seal between the moving surfaces of hydraulic cylinders, which is necessary to prevent fluid bypass and preserve the operating pressure required for the machine to function correctly.
This component is compatible with the Demag AC80-1 model. It acts as a primary seal for either the piston or the rod assembly within the hydraulic circuit, ensuring that the system maintains its integrity during operation.
In hydraulic machinery, a Glydring functions by providing a seal that manages the interface between moving parts under pressure. By maintaining this barrier, the seal helps ensure that hydraulic force is effectively translated into mechanical movement without loss of fluid or pressure drop across the cylinder assembly.
