Piston seals

Piston seals seal the two cylinder chambers separated from the piston and prevent fluids from escaping from the cylinder. A basic distinction is made between single and double-acting sealing elements. We have a large selection of profiles and material combinations for use in hydraulics or pneumatics.

Wiper seals

Single or double-acting wipers are installed in hydraulic cylinders to remove dirt, foreign particles, swarf and moisture from the piston rod entering the system. This extends the service life of the seals and helps to protect the guide parts. Our sealing systems offer suitable wipers with maximum reliability and durability for all types of cylinders and applications.

Rotor seals

Rotor seals are used to seal rotary and swivelling movements of shafts, often under high pressure, against operating fluids such as water, oil and grease. Mainly used in mechanical engineering and the construction machinery industry, a distinction is made between internal and external seals. We offer a wide selection of the right sealing element for your application.

Back-up rings  provide the primary seal with optimum protection against extrusion under high pressure loads. This prevents the O-ring from penetrating into the sealing gap. We offer a wide range in endless, slotted or spiralised designs.

Guide rings, on the other hand, as the name suggests, are used to guide the pistons or rods of a hydraulic cylinder. They also compensate for the sometimes high lateral forces, prevent metal-to-metal contact and thus optimise the performance and service life of the sealing system.
