DHS Hydraulic Seals- Dust seals

Short Description:

DHS wiper seal is a lip-seal for Rod which fits tightly in the groove..The seal of the hydraulic cylinder is installed on the shaft of the hydraulic pump and the hydraulic motor to prevent the working medium from leaking along the shaft to the outside of the shell and the outside dust from invading the inside of the body in the opposite direction.The axial movement of the hoist and the guide rod. DHS Wiper Seal is to do reciprocating piston movement.

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 sealing quality and service life of a shaft seal depend to a large extent on the surface condition of the counter sealing surface. The counter sealing surfaces must not show any scratches or dents.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.
DHS Hydraulic Rod Seals made from polyurethane. All our seals are packed and sealed at the point of manufacture to ensure the highest quality. They are stored out of sunlight and kept in a temperature controlled environment until dispatch.
