Wiper seal for Demag AC80-1

The wiper seal, part number 410 197 12, serves as a protective component within the hydraulic systems of the Demag AC80-1 crane. It is installed at the cylinder head to clean the surface of the piston rod as it retracts into the cylinder housing. By removing dust, dirt, moisture, and other debris from the rod, the seal prevents these contaminants from entering the primary sealing system and the hydraulic fluid circuit.

This component is compatible with the Demag AC80-1 model. It functions by creating a barrier that stops external particles from reaching the internal seals and bearings, which helps prevent premature wear and scoring on the rod surface. By maintaining a clean rod, the wiper seal assists in preserving the integrity of the internal hydraulic seals and maintaining the operational pressure of the cylinder assembly.

Wiper seals are used in hydraulic and pneumatic actuators to protect internal components from environmental exposure. Their primary role is to ensure that only a clean rod enters the cylinder, thereby reducing the risk of leakage and extending the service interval for the hydraulic system.
