Rod Seals

Rod Seals from Freudenberg Sealing Technologies perform multiple tasks

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. Freudenberg Sealing Technologies offers the right Rod Seal for every kind of cylinder and application.

Maximum efficiency from the best possible combination

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 (see example in Fig. 1). The so-called primary seal faces the cylinder’s working space and reliably seals against the high operating pressure within the cylinder.
