Parker AF-type metal skeleton dust ring
  AF type ULTRATHAN dust seal to prevent dust, dirt, sand, metal debris from entering the hydraulic cylinder. It reduces the risk of contamination due to external scratches caused by the sliding element is embedded. Through a specially designed dust lip, it has an excellent effect of dust. Verified by the use of polyurethane material P5008 has strong wear resistance, 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 flush with the end portion of the cylinder head, by a lip on the external causes of damage are highly protective.

  From an engineering standpoint, AF dust ring is a suitable cylinder head sealing device, which seals the system configuration and B3 and BU rod seals, have been under the most adverse environmental conditions and experimentally confirmed.

1. Material:
  Standard materials rubber element is 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.

If the special requirements (temperature, velocity, for water, HFA solution, HFB and other liquid media), please contact our service department in order to recommend the right materials and structures.

2. Application:
 Hydraulic cylinders and valves
  Operating temperature: -35 ° C to + 100 ° C
  Surface speed: ≤2 m / s

3. Install:
 AF type ULTRATHAN dust ring is slightly larger outside diameter D can ensure the formation of a trench Dh8 reliable tight fit after installation. Avoid dust seal lip in contact with the piston rod eyelet or other connecting elements.
