4. FAQ

Q: Can this piston rod seal be installed on hydraulic cylinders of all construction machinery?
A: It is tailor-made for wheel loader lift cylinders. It cannot fit excavator travel cylinders or motor grader steering cylinders of different specifications.

Q: What kinds of operation sites are suitable for this hydraulic piston rod seal?
A: It adapts to sand yards, cargo terminals and bulk material loading sites, coping with heavy lifting loads and dusty working surroundings.

Q: How about the temperature adaptability of this sealing assembly?
A: It can work steadily within the temperature range of -75°C ~ 368°C and keep reliable sealing performance under continuous heavy lifting circulation.

Q: What preparation work should be completed before installing this piston rod seal?
A: Inspect the surface smoothness of the piston rod. Any scratches will accelerate abrasion and shorten the service life of the new seal.

Q: What typical hydraulic troubles can this piston rod seal help avoid?
A: It effectively reduces external hydraulic oil leakage and prevents permanent extrusion deformation under frequent load pressure changes.

Q: How well can this sealing set block construction mud, rock dust and suspended hot hydraulic oil mist in muddy outdoor excavation working conditions?
A: The outer NBR dust wiper intercepts large sediment particles, while the inner PU main seal isolates hot oil mist inside the cylinder, and wear-resistant PTFE rings avoid scratch damage from fine grit mixed in hydraulic oil.

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.
