More about Rod seals

Rod seals play a decisive role in the reliable operation of hydraulic cylinders, ensuring controlled sealing performance even under demanding pressure conditions. Their function is to retain the operating medium within the cylinder during rod movement while preventing leakage to the outside environment.

During operation, a thin lubricating film forms on the rod surface, supporting surface protection and creating favorable conditions for smooth interaction between sealing and wiping elements.

Modern rod sealing solutions are designed with flexibility in mind. Depending on application requirements, they may be supplied as compact single designs or as multi-component sealing arrangements combining several functional elements. The use of low-friction, high-performance materials ensures long service life, reliable function, and stable performance in challenging operating conditions.
