Hydraulic Support System Seals

                                                           Sealing repair kit for mining hydraulic support

features:
Excellent wear resistance is insensitive to impact load and pressure value
High extrusion resistance
Low permanent compression deformation
Simple installation of seals
The sealing of mining hydraulic support is mainly used for the sealing of mining hydraulic cylinder and sealing repair kit.

                                                                                                                                  Hydraulic support seal                                                                                                                                           

Hydraulic support seal repair kit

Operating conditions:

Material: polyurethane

Temperature: - 35~100 ℃

Speed:=0.5m/s

Working pressure: ≤ 40mpa

Working medium: hydraulic oil

Design description:

SRu adopts asymmetric double-lip piston rod seal structure to provide the most suitable seal in light and medium load applications

effect. When the seal is used together with the sRT support gasket, it can be applied to the heavy-load seal.

This seal is divided into low temperature resistant type and high temperature resistant type:
