Seal ring for Demag AC80-1

The seal ring, identified by part number 356 136 40, serves as a barrier between two mating surfaces within the Demag AC80-1 crane. Its primary function is to maintain a hermetic seal that prevents the escape of hydraulic oil or lubricants while simultaneously blocking the entry of dust, moisture, and other contaminants into the machine's internal assemblies. By maintaining this seal, the component helps preserve the integrity of the system it serves.

This part is compatible with the Demag AC80-1 model. Seal rings of this type are commonly utilized throughout various crane systems, including hydraulic circuits, transmission housings, axle assemblies, and bearing housings. In these applications, the ring ensures that operating pressures are maintained and that moving parts receive consistent lubrication. Proper sealing is necessary to prevent fluid loss and to protect sensitive mechanical components from premature wear caused by environmental debris or loss of internal pressure.
