4. FAQ

Q: What material constitutes the main sealing body of this piston rod seal?
A: The primary sealing component adopts almond fiber reinforced HNBR elastomer, equipped with zirconium filled PTFE wear-resistant ring and POM backup ring for matched assembly.

Q: What color presentation can we observe on each sealing part?
A: The main rod seal is low-gloss deep black, the PTFE support ring is snow white, and the backup ring shows neutral light grey.

Q: Can this piston rod seal fit hydraulic cylinders of all construction machinery?
A: It is specially manufactured for excavator bucket cylinders. It cannot be mounted on wheel loader steering cylinders or bulldozer tilt cylinders of different dimensions.

Q: What construction working scenarios suit this hydraulic piston rod seal?
A: It applies to quarry excavation and soil loading sites, coping with frequent bucket grabbing and dumping movements and sediment erosion.

Q: How about high and low temperature adaptability of this sealing assembly?
A: It maintains stable sealing performance within -77°C to 371°C and works reliably under long-term cyclic loading operations.

Q: What installation tips should operators follow during replacement?
A: Clean all impurities inside the cylinder thoroughly. Tiny particles will scratch the sealing lip and shorten service life rapidly.

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.
