Parker BD type rod seals
BD type ULTRATHAN ® rod seal is a seal Pike PARK-O-PAK ® further development outcomes, it has two sealing lip, and there is a very strong retaining ring anti-extrusion. Since the two sealing lip role in the sealing gap will keep this additional lubrication. (This greatly reduces the ground dry friction and wear, thus extending the service life of the seal.)
Under certain conditions, it is available only to achieve satisfactory sealing performance by one after two seals mounted in each trench. BD This two lip seals but it can replace expensive tandem devices. Such seals can be used for ordinary rubber or fabric reinforced rubber physical properties meet the requirements of various occasions.
The main advantages are:
● excellent wear resistance.
● impact resistance, anti-extrusion.
● compression deformation.
● suitable for the most demanding working conditions.
● due to the pressure of the sealing lip between the media having sufficient lubrication.
● improve the sealing performance under zero pressure.
● Excellent preventing the outside air from entering.
● Easy to install.
1. Material:
Parker polyurethane material P5008 is a Shore A hardness of about 93. NBR-O-ring Shore A hardness of about 70.
By a collar filled polyamide (W5019) was obtained.
2. Application:
Working pressure: ≤500bar (peak 1000bar)
Operating temperature: -35 to + 110 ° C
Surface speed: ≤0.5m / s
Media: Hydraulic oil (mineral oil based)
Mainly used in mobile machinery and heavy-duty hydrostatic piston rod and piston seal.
3. Install:
Such a seal should have an axial clearance (see columns H and L). To avoid damage to the sealing lip, the installation will not pull the seal sharp edges.
These seals are usually loaded closed groove. When restricted entrance, you need special installation tools. If the user requirements, the company will provide tools such as design, tolerance guidelines H8 /f7.
For special requirements (pressure, temperature, velocity, etc., used water, HFA solution, HFB and other liquid media), please contact our service department in order to recommend the right materials and structures.
