Rod seals are primarily used in pneumatic and hydraulic cylinders and have the task of sealing the incoming and outgoing cylinder rod. The goal is to prevent the escape of the pressurized operating medium from the cylinder. At the same time, it must be protected against external contaminants. We Offer the right rod seal for every kind of cylinder and application.Rod seals from Freudenberg Sealing Technologies are used in state-of-the-art sealing systems for cylinders of all kinds. They are specially adapted to the respective conditions of use and tasks while meeting customers’ high expectations for maximum reliability, service life and functionality. State-of-the-art hydraulic rod sealing systems generally consist of several individual seals. The so-called primary seal faces the cylinder’s working space and reliably seals against the high operating pressure within the cylinder.The secondary rod seal fitted behind it takes over the main sealing function. It is above all designed to reduce the residual oil film on the rod to a minimum during its extension. Seals constructed of polyurethane are preferably used for this task. With their defined sealing lip, they ensure the finely tuned wiping of the medium, guaranteeing the leak tightness of the cylinder toward the exterior.wipers are used as a third element in the rod sealing system, in addition to the guide elements that prevent the contact of the incoming and outgoing rod with the housing. Their task is to protect the systems’s primary and secondary seals from external contamination and influences. In addition, static seals are needed for the cover/cylinder housing intersection.
