DK type is a dual U-shaped seal and metal skeleton vulcanization bonding integral pneumatic piston. It has two functions: sealing and guide.

Advantage

• can be simply fixed on the piston rod, without additional sealing requirements.

• All the rubber coating, difficult to corrosion.

• Since the ventilation channel structure, it can quickly respond to (full pressure load).

• Due to the geometry of the sealing lip can be maintained lubricant film, low friction, smooth operation.

• Can be used for oil-lubricated and oil-free air through the air initially lubricated.

• it also has the same single-acting piston seal seal size EK Available.

Applications

DK integral piston, can be used with or without a buffer end double-acting cylinder, long stroke and bending conditions, can not withstand excessive loads.

Working Pressure: 16bar

Operating temperature:

         Standard materials Z5051: -30 to + 80 ℃

         Standard materials Z5071: -35 to + 80 ℃

Surface speed: 1m / s

Media: oil lubricated and oil-free air through the air initially lubricated.

Material

Standard material is a synthetic rubber (NBR group), Shore A71, and vulcanization bonding with metal skeleton. When the bore is greater than 100mm, it is recommended as the material hardness of Shore 78A.

Installation

DK pneumatic piston integral use locking nut secured to the piston rod so as not to loose, dry and free of oil for air, the piston and cylinder should adopt suitable long-life lubricant pre-lubricated.

Make sure the sealing lip at the stroke end there is enough space for free movement (reference dimension table "Ødm").

For special requirements (temperature, speed, used for water, HFA solution, HFB fluid, etc. medium), please contact our service department in order to recommend appropriate materials and structures.

The above data are in standard materials and standard media measured. Require specific temperature range depending on the application conditions.
