4. FAQ

Q: Can this piston rod seal be mounted to hydraulic cylinders of all construction machinery?
A: It is specially manufactured for grader tilt cylinders. It cannot fit excavator stick cylinders or wheel loader steering cylinders of different structural sizes.

Q: What core function does this seal perform during machine operation?
A: It restricts hydraulic oil escaping along piston‑rod clearance and copes with variable working pressure from material‑loading cycles.

Q: Can this composite seal sustain continuous reciprocating movement under heavy‑load earth‑moving conditions?
A: Low‑friction PTFE surface reduces frictional heat, so it keeps stable sealing performance under frequent cyclic movement.

Q: Are these rod seals manufactured according to standard hydraulic cylinder groove dimensions?
A: Every piece is precision processed to match standard gland groove size for wheel‑type scraper hydraulic assemblies.

Q: Will long‑time back‑and‑forth rod movement bring obvious abrasion to the sliding layer?
A: Filler‑modified PTFE improves anti‑abrasion capacity and slows lip wear under continuous reciprocating strokes.

Q: Will continuous back‑and‑forth rod movement cause rapid abrasion on the sliding surface?
A: Modified PU formula improves sliding property, lowers friction loss and extends service life under repeated reciprocating motion.

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.
