Type GBD

GBD type xipulis piston rod seal is a perfect development result of lip seal. It has two sealing lips and a retaining ring with strong extreme pressure resistance. Due to the function of the two sealing lips, it is maintained in the sealing gap. The additional lubrication prevents dry friction and wear, and prolongs the service life of the seal. Under certain conditions, satisfactory sealing performance can only be achieved by two seals installed in their respective grooves one after the other, while these two lip seals can replace expensive tandem devices.

Main advantages:
● Good wear resistance
● Anti-extrusion
● Impact resistance
● Small compression deformation
Adapt to harsh working conditions
● Adequate lubrication due to the pressure medium between the sealing lips
● Improved sealing performance under zero pressure
● Prevent the entry of outside air
● Easy installation

Scope of application:
Working pressure: ≤ 50Mpa
Working temperature: -35~120 ℃ (peak value up to 140 ℃)
Surface speed: ≤ 0.5 m/s
Hardness: 95A ± 2
Mainly used for heavy-duty walking machinery and static pressure in the piston rod and plunger seal.
Material: XA-6095 is a kind of A95 high temperature resistant polyurethane composite material, 0-ring is 70A NBR material.
Installation: This type of seal should have axial clearance, in order to avoid damage to the sealing lip, do not install the seal on the sharp edge. Pull up.
