Q: What raw materials constitute this piston rod seal assembly?
A: The primary sealing body adopts cedar fiber reinforced FKM elastomer, matched with chromium filled PTFE sliding ring and flexible modified POM backup ring for assembly.

Q: What color differences can we observe among each sealing component?
A: The main piston rod seal is semi-matte dark black, the PTFE sliding ring is light beige, and the backup ring presents pale ash grey.

Q: Can this piston rod seal be universally installed on hydraulic cylinders of all construction machinery?
A: It is specially manufactured for wheel loader bucket cylinders. It cannot fit bulldozer tension cylinders or grader steering cylinders with different structural specifications.

Q: What working conditions fit this hydraulic piston rod seal well?
A: It works reliably in gravel yards and port loading sites, adapting to frequent material grabbing operations and environments mixed with fine sand and muddy water.

Q: How is the temperature adaptability of the whole sealing assembly?
A: It maintains stable sealing efficiency ranging from -65°C to 363°C under continuous day-and-night loading operation of wheel loaders.

Q: What advantages does cherry fiber reinforced HNBR have compared with ordinary nitrile rubber?
A: It possesses excellent dynamic abrasion resistance and elastic recovery, suitable for continuous reciprocating motion of travel motor 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.
