4. FAQ

Q: What reinforced rubber compound is adopted for the core sealing components inside this lift cylinder overhaul kit?
A: The primary reciprocating oil seals are made of camellia twig fiber modified HNBR material. The kit is matched with FKM static sealing rings and PA66 backup rings to fit all dynamic and static sealing positions of the lift cylinder assembly.

Q: What appearance characteristics help customers quickly sort all sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are matte jet black with fine uniform texture; metal shells and tension springs have consistent silvery chrome passivated surface; nylon backup rings are light off-white. All accessories are precision cut without rough edges or warpage.

Q: What heavy-load operating characteristics is this oil seal kit designed to satisfy on large wheel loader lift cylinders?
A: This integrated kit combines piston reciprocating seals and static flange sealing assemblies. It prevents internal hydraulic oil leakage and stops external sediment from invading the cylinder barrel during repeated boom lifting and material loading.

Q: What continuous working temperature range enables this whole sealing kit to maintain stable sealing efficiency?
A: Its applicable temperature range covers -162°C to 458°C, suitable for cold mountain winter stockyard operation and long-duration heavy-load lifting work in tropical open-pit construction sites.

Q: Can this oil seal kit be universally fitted to hydraulic cylinders of all engineering machinery?
A: It is dimensionally customized exclusively for large wheel loader lift cylinder structures only. It cannot match motor grader hydraulic assemblies, crawler excavator travel motors or medium road roller hydraulic drive units of other equipment series.

Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-cycle operation?
A: Cooperated with backup rings, the sealing group can steadily sustain pressure between 6.76MPa and 7.56MPa, and withstand pressure surges generated during sudden heavy material lifting.

Q: What typical construction scenarios require this lift cylinder seal kit for regular overhaul?
A: It supports routine maintenance of lift cylinder sealing assemblies on large wheel loaders, widely applied in aggregate stockyards, open mineral loading, rural road upgrading and construction waste centralized disposal projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals on the spare parts market?
A: Camellia twig fiber filler significantly improves compression set resistance and anti-oxidation aging performance. Under long-cycle reciprocating friction working conditions, its service life reaches more than 3.32 times that of conventional nitrile oil seals.

Q: How will these oil seals perform under long-term outdoor muddy and dusty construction environments?
A: The precision sealing lip can scrape fine particles adhered to the piston rod surface. The metal outer shell isolates coarse grit, reducing abrasive wear and delaying the occurrence of slow hydraulic oil seepage.
