Hydraulic Rod Seals
The hydraulic rod seals are used for hydraulic cylinders and actuators keeping the applied system pressure from leaking into the surrounding environment.
The goal of the hydraulic rod seals is to prevent leakage and, as a result, pollution of the surrounding environment. They come in single-acting and double-acting varieties.
A tandem rod sealing system with a buffer seal is typically required for high-pressure applications. In the cylinder sealing system, the hydraulic rod seals generally interact with wiper components.
To match the unique application profile, a broad range of compound and profile combinations are offered. Rod seals that meet ISO 6020, ISO 5597, and ISO 7425-2 requirements are available.

What are the primary functions of hydraulic rod seals in hydraulic cylinders?
Hydraulic rod seals are essential components in hydraulic cylinders, designed to prevent fluid leakage from the cylinder into the environment. Their primary function is to maintain the integrity of the hydraulic system by keeping the applied system pressure contained, thus preventing contamination and ensuring optimal performance. They are available in both single-acting and double-acting designs, allowing for versatile applications.
How does the choice between a single-acting and double-acting hydraulic rod seal impact system performance?
The choice between a single-acting hydraulic rod seal and a double-acting hydraulic rod seal significantly impacts system performance. A single-acting seal is designed to seal fluid in one direction, suitable for applications where hydraulic force is applied in a single direction. In contrast, a double-acting seal can seal fluid in both directions, providing greater flexibility and efficiency in applications that require movement in two directions, thereby enhancing overall system effectiveness.
What considerations should be taken into account when selecting hydraulic rod seals?
When selecting hydraulic rod seals, it is crucial to consider factors such as the operating pressure, temperature range, and compatibility with the hydraulic fluid. Additionally, the choice between single-acting and double-acting seals should be based on the specific application needs. Proper selection ensures optimal sealing performance, reduces the risk of leakage, and prolongs the lifespan of hydraulic components.
