Rod Seal is used in hydraulic cylinders for fluid sealing. They are external to the cylinder head and seal against the cylinder’s rod, preventing leakage of fluid from within the cylinder to the outside.
Rod seals for hydraulic cylinders seal the system pressure on the rod side of the cylinder against the atmosphere. They seal the pressures during the stroke phase and position holding operation of the cylinder.
The individual profile design shows specific behaviors and performance which need to be in line with the application´s requirements. There are single or tandem designs of reading sealing systems. The rod sealing system considers also the wiper and the guiding elements.
The rod seal is the most critical seal on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside. Leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issues. DLseals offers a wide range of hydraulic rod seals for both single-acting and double-acting systems.
