Sealing ring for Demag AC80-1

The sealing ring, part number 501 637 98, serves as a barrier between mating surfaces within the Demag AC80-1 crane. By maintaining a hermetic seal, it prevents the escape of pressurized hydraulic oil, lubricants, or gases from the internal systems of the machinery. This component is used in various assemblies across the crane, including hydraulic circuits, transmission units, and engine systems, to ensure that fluids remain contained and contaminants are excluded from the internal mechanisms.

This specific sealing ring is compatible with the Demag AC80-1 model. It is designed to fit precisely within the designated housing to maintain system pressure and prevent fluid loss during operation. Proper installation of this ring is necessary to ensure the continued integrity of the crane's hydraulic and mechanical systems.

Sealing rings are used throughout heavy machinery to bridge the gap between two parts, preventing leakage and maintaining the pressure required for the system to function correctly. They are typically found in cylinders, pumps, and valves, where they provide a static or dynamic seal to manage fluid flow and protect internal components from external environmental factors.
