Parker BR type rod seals

   BR type ULTRATHAN ® rod seal is a compact seal with retaining ring. This seal is mainly used in construction machinery cylinder seal system, used as a buffer seal. In extreme conditions, the cylinder pressure is often up to 1000bar, BR will be separated from the main rod seal type seal with such a load. Because it has a special structure, which can be in a pressure seal is formed between the primary seal and the seal of the buffer passed back into the system.

The main advantages:

· Wear especially good.

· Impact

· Anti-extrusion

Compression deformation

Be able to adapt to the most demanding working conditions

· Easy to install

· Load international standard ISO7425 / II seal groove design.

1. Material:

 P5008 is a polyurethane material Shore A hardness of about 93.

 Collar Material: Polyamide

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

 
2. Application:

 Mainly used in mobile hydraulic cylinder seals.

Working pressure: ≤500bar (pressure peaks up to 1000bar)

Operating temperature: -35 ° C to + 110 ° C

Surface speed: ≤0.5m / s

Media: Hydraulic oil (mineral oil based)

3. Install:

 Such seals should be axial clearance (see Table H and L). To avoid damage to the sealing lip, the installation will not pull the seal sharp edges.

 Such seals generally can be loaded into closed groove. When the entrance is restricted to use special installation tools. If user requirements, the company will provide design of such tools, tolerances H8 / f7.
