5. FAQ
Q: What core sealing responsibility is undertaken by PU inside the excavator’s stick hydraulic cylinder?
A: Serving as the primary dynamic sealing core, PU takes advantage of stable elastic recovery to prevent hydraulic medium leakage as the machine’s stick stretches out and retracts repeatedly to pry and gather hard mineral stones under continuous variable digging resistance.

Q: What is the core development purpose of matching kaolin-filled PTFE as auxiliary backup ring alongside the primary PU seal?
A: It fills micro gaps inside piston installation grooves and shields soft PU from being squeezed and fractured by instantaneous hydraulic pressure spikes triggered when the stick hits rigid bedrock accidentally during high-intensity mining excavation.
Q: What prominent performance edges make FKM fluororubber surpass regular conventional NBR rubber materials?
A: FKM possesses outstanding thermal aging resistance and chemical corrosion resistance, maintaining stable dimensional precision even after long-term immersion in overheated, impurity-contaminated deteriorated hydraulic oil from round-the-clock nonstop mining operation.
Q: At which specific fixed positions of cylinder assembly are FKM rubber O-rings commonly arranged for installation?
A: FKM small rubber pieces are mainly deployed for static sealing on high-heat connecting flange surfaces of cylinder end caps and threaded joint gaps of high-pressure hydraulic pipelines.
Q: What practical running optimization can linen base phenolic impregnated fabric wear ring bring to piston reciprocating movement?
A: It restricts piston lateral offset and side sway during stick telescopic actions, maintains consistent piston concentricity and effectively lowers long-term abrasive scratch between piston outer circumference and cylinder inner tube wall.
