GBD type piston rod seal for heavy-duty walking machinery and static pressure

The GBD-type HG piston rod seal is the most perfect development results of the most perfect lip seal. It has two sealing lips, and has a strong anti-polar pressure.Due to the role of the two sealing lips, the additional lubrication is maintained in the sealing gap to prevent dry friction and wear, and the service life of the seal is extended.

Under certain conditions, only the seals mounted in the respective trenches can achieve satisfactory sealing performance by one of the two labels, while the seals of the two lips can replace the price expensive series device.

Main advantage:

▪ It is extremely wear resistance. 

▪ Extrude.

▪ Impact resistance.

▪ Small compression deformation. 

▪ Applicable to a harsh working environment.

▪ It has sufficient lubrication due to the pressure medium between the sealing lip.

▪ Improve the sealing performance under zero pressure .

▪ It is best to prevent external air from entering .

▪ Easy to install.

Application range:

 Working pressure: ≤50MPa

 Working temperature: -35 ~ + 120 ° C (peak up to 140 ° C)

 Surface speed: ≤0.5m / s

 hardness: 95A ± 2

Mainly used to override the seal of the piston rod and plunger in the traveling machine and the static pressure.

Material: Xa-6095 is a NBR material having a high temperature polyurethane composite of A95, an O-ring of 70A.

Installation: Such seals should have an axial gap to avoid damage to the sealed lip, do not pull the seal on the sharp edges.
