Wipers AS is the standard dust seal

Wipers AS dust ring is a rubber ring with a metal skeleton, the role is to prevent dust, dirt, sand or metal debris into the hydraulic cylinder. Reduce the risk of scratches cause d by external contaminants embedded in sliding elements. Excellent dust proof effect can be achieved by the special design of the lip of the dust proof ring. Seals that maintain the normal operation of equipment and maintain the sealing performance of components. Wipers AS dust ring lip made of nitrile rubber or polyurethane materials, with high dust performance of the standard dust seal.

Wipers AS dust ring , It has been proved that polyurethane rubber has the characteristics of strong wear resistance, small permanent deformation and external mechanical impact, And the dust ring can be firmly installed in the appropriate position of the axial open trench by using the interference fit between the outer diameter of the sealing groove and the metal. Because the lip of the dust ring is flush with the end of the cylinder head, the lip is highly protective against damage caused by external reasons.

Note
The piston rod surface should be polished and ground, especially under harsh conditions.

Installation
Wipers AS Dust ring is an appropriate cylinder head sealing device from the perspective of engineering. Wipers AS dust ring has a slightly larger outer diameter, which can ensure that a reliable tight fit is formed in the groove after installation. The contact between the lip of the dust ring and the hole of the piston rod or other connecting elements should be avoided.
