DMH Dichtung Stangendichtung

The product

The rod seal is the most critical seal in a cylinder and primarily has the task of withstanding high pressures. It should seal the retracting and extending piston rod to such an extent that the pressurized operating medium is prevented from escaping from the cylinder into the environment. The remainder of the entrained liquid film should be left on the sliding surface of the rod, firstly to protect it from corrosion and secondly, to lubricate the sealing edge of the rod seal and the wiper lip of the wiper. DMH rod seal systems offer high efficiency and lifespan. They consist of rod seals and upstream seals. Depending on the application, they are designed as one-piece U-cups or lip seals or as multi-part compact sealing systems in low-friction high-tech material grades.
