Step seal for Demag AC80-1

The step seal, identified by part number 410 199 12, acts as a sealing component within hydraulic systems. Its primary function is to contain hydraulic fluids such as oil or grease while preventing external contaminants from entering the system. This seal is engineered to maintain pressure and support the movement of internal components within the hydraulic assembly of the machine.

This component is compatible with the Demag AC80-1 all-terrain crane. It is typically installed within hydraulic cylinders, including those used for boom operations, outriggers, or steering systems, to ensure precise and controlled movement of the crane's mechanical parts.

In hydraulic systems, step seals are used to manage the interface between moving parts, such as a piston and a cylinder bore. By maintaining a tight seal, they prevent pressure loss that could otherwise lead to erratic operation or reduced system efficiency. These seals are designed to operate effectively under the pressure and speed conditions common in heavy machinery hydraulic circuits, helping to preserve the integrity of the fluid power system during operation.
