AQ-Seal piston seal for Demag AC80-1

The AQ-Seal piston seal, part number 978 367 73, serves as a sealing element within the hydraulic cylinder assemblies of the Demag AC80-1 crane. Its primary function is to provide a barrier between the cylinder chambers, preventing fluid bypass and maintaining the internal pressure required for the piston to perform linear movements. By ensuring this separation, the seal allows the hydraulic system to convert fluid pressure into the mechanical force needed for crane operations.

This component is compatible with the Demag AC80-1 model. It is engineered to maintain its sealing function within the cylinder environment, helping to manage fluid containment during operation. Proper installation and maintenance of the piston seal are necessary to support the functionality of the hydraulic cylinders and the overall performance of the machine's lifting and positioning systems.

Piston seals are used in hydraulic cylinders to prevent fluid leakage across the piston head. They are designed to withstand the pressure differentials present during the extension and retraction cycles of the cylinder, which is essential for the controlled operation of heavy machinery actuators.
