Rod Seals

Dynamic and Static Sealing of the Piston Rod Towards the Cylinder

Rod seals are used for sealing of retracting and extending cylinder rods. This prevents the pressurized process media from escaping from the cylinder. In addition, the cylinder is reliably protected against dirt, dust or any fluids. Due to the wide range of requirements in hydraulic applications, such as pressure, pressure peaks, sliding speeds, temperatures, and process media, choosing the right rod seal is very important. The Dichtomatik product brand portfolio offers a wide range of elastomer and thermoplastic rod seals, such as the N, S, SNI, SDS, SPOR series. Typical applications for Dichtomatik rod seals are hydraulic cylinders in mobile hydraulics, agricultural machinery, construction machinery and presses.
