Parker AG metal skeleton dust ring
  AG type ULTRATHAN ® metal skeleton dust ring to prevent dust, dirt, sand, metal debris into the hydraulic cylinder rod end ball bearings, thus reducing the risk of contamination due to external invasion of scratching rotation pin. Through a specially designed dust lip, it has an excellent effect of dust; in addition to the lubrication, dust lip can be opened to release the excess grease. Verified by the use of polyurethane material P5008 with good wear resistance, small compression permanent deformation, an external mechanical shock resistance characteristics. By interference fit of the outside diameter of the trench with a metal ring, dust ring can be securely mounted in axially open groove. Since the dust lip and shaft end flush with the lip of the damage caused by external causes highly protective.

1. Material:

Standard materials for the P5008, which is a polyurethane material Parker Shore A hardness of about 93. Compared with other polyurethane materials currently on the market, to improve the heat resistance, resistance to hydrolysis capacity enhancement.

2. Application:

Hydraulic cylinders and valves

Working temperature: -35 ℃ to + 100 ℃

Surface speed: ≤2m / s

3. Install:

AG ULTRATHAN type dust ring is slightly larger outside diameter D, formed after the installation can ensure a reliable tight fit in the groove D H8. Avoid contact with dust lip ring and the piston rod eyelets or other elements.
