4. FAQ

Q: What raw materials construct this piston rod seal assembly?
A: The primary sealing body adopts birch fiber reinforced FKM elastomer, equipped with vanadium filled PTFE sliding ring and balanced rigid modified POM backup ring for matched assembly.

Q: What color differences can be seen among all sealing components?
A: The main rod seal is matte jet black, the PTFE sliding ring is light ivory, and the anti-extrusion backup ring displays soft light grey tone.

Q: Can this piston rod seal be fitted onto hydraulic cylinders of various construction machines?
A: It is specially engineered for wheel loader steering cylinders. It cannot adapt to excavator stick cylinders or grader lift cylinders of different structural dimensions.

Q: What working environments suit this hydraulic sealing component best?
A: It performs steadily at cargo terminals and aggregate storage yards, coping with frequent steering adjustment and dusty open-air operating conditions.

Q: How is the high and low temperature stability of this complete sealing set?
A: It maintains consistent sealing efficiency within -62°C ~ 362°C during long-hour continuous material handling work of wheel loaders.

Q: Which installation details should maintenance technicians pay attention to?
A: Clear all metal burrs on the piston rod surface. Sharp edges will continuously scratch the sealing lip and shorten service life significantly.

Q: What common hydraulic defects can this piston rod seal effectively prevent?
A: It suppresses outward hydraulic oil leakage and avoids irreversible extrusion deformation caused by frequent pressure fluctuation during steering actions.

Q: What core performance strengths does pine fiber reinforced FKM have compared with regular sealing rubber?
A: It features excellent resistance to hydraulic fluid corrosion and anti-fatigue property, matching frequent reciprocating motion of excavator stick cylinders.

Q: What unique advantages does apricot fiber reinforced FKM have compared with traditional sealing rubber?
A: It delivers excellent oil corrosion resistance and thermal stability, perfectly adapting to high-frequency movement of excavator boom cylinders.

Q: What practical efficiency benefits can on-site excavator maintenance staff gain from using this fully pre-matched rod seal kit?
A: All supporting sealing accessories required for rod overhaul are pre-assembled into one complete set without separate procurement. Technicians do not need to carry scattered loose seals or repeatedly measure rod groove dimensions on site, greatly shortening cylinder repair time.
