Wipers
Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.
Contamination can cause significant damage to the rod, cylinder wall, seals, and other components, and is one of the primary causes of premature seal and component failure in a fluid power system.
The wiper seal is the most undervalued seal type in the hydraulic cylinder in relation to its important function. Particular attention should be drawn to its selection, the surrounding environment and service conditions must also be taken into special consideration.
