5. Adantage:
The AF dust ring is used to prevent dust, dirt, sand particles, and metal debris into the hydraulic cylinder. Reduce the risk of scratching due to external pollutants embedded in sliding elements. Through the special design of dust -proof lips, it has an excellent dustproof effect. After verification, polyurethane material P5008 has the characteristics of strong abrasion resistance, small permanent deformation, and impact of external mechanical impact. Through the aggregation of the outer diameter of the metal ring, the dustproof ring can be reliable in the axial open groove. Due to the flatness of the dust -proof exhibition and the end of the cylinder head, the lip mouth is highly protected on the damage caused by external reasons.
From the perspective of the project, the AF dust ring is a suitable tank head sealing device. The sealing system composed of the B3 and BU live club seals has been tested and confirmed in the worst working environment.
6. INSTALLATION:
The outer diameter D of the AF type Ultrathan dust ring D is slightly larger, which can ensure that a reliable tightening is formed after installation in the groove D. Avoid contact with the dust ring lip mouth and the piston pore eye or other connected elements.
