The step seal, identified by part number 978 368 73, serves as a dynamic sealing element within the hydraulic systems of the Demag AC80-1 crane. This component is engineered with a specific stepped profile that facilitates effective sealing against fluid bypass, ensuring that hydraulic pressure is maintained during operation. By preventing leakage and blocking external contaminants, it protects the internal surfaces of hydraulic cylinders and associated components from premature wear.
This seal is compatible with the Demag AC80-1 model. It is designed to fit into specific grooves within the hydraulic circuit to manage fluid containment under varying pressure conditions. The geometry of the seal allows it to maintain contact with sliding surfaces, which is necessary for the precise operation of crane controls and lifting functions.
In heavy machinery, step seals are commonly utilized in dynamic applications where reciprocating motion occurs. They provide a barrier that separates fluid chambers while accommodating the movement of piston rods or cylinder heads. Proper installation of these seals is necessary to ensure the hydraulic system operates at the intended efficiency levels, supporting the overall functionality of the machine's hydraulic power transmission.
