4. FAQ

Q: What material is adopted for the primary sealing main body of this piston rod seal?
A: The main sealing component uses apricot fiber reinforced HNBR elastomer, matched with chromium filled PTFE wear-resistant ring and POM anti-extrusion backup ring for assembly.

Q: What color differences can be seen among each sealing component?
A: The main rod seal presents low-gloss black, the PTFE support ring is ivory white, and the backup ring shows light charcoal grey.

Q: Could this piston rod seal be universally installed on hydraulic cylinders of other engineering machinery?
A: It is specially designed for excavator arm cylinders. It cannot be applied to bulldozer tilt cylinders or wheel loader steering cylinders of different sizes.

Q: What construction working conditions suit this hydraulic piston rod seal?
A: It performs steadily in mountain excavation and foundation engineering sites, coping with frequent arm stretching movements and muddy environment erosion.

Q: How is the high-low temperature resistance of this sealing assembly?
A: It maintains reliable sealing performance from -76°C to 372°C and works continuously under long-time heavy load excavation operations.

Q: What key points should technicians notice during installation?
A: Avoid scratching the sealing lip with sharp edges during mounting. Tiny scratches will cause oil leakage and shorten service life significantly.

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.
