5. FAQ

Q: What frequent reciprocating load working conditions is this oil seal kit designed to adapt to on HG110 motor grader lift cylinders?
A: This integrated kit combines piston reciprocating seals and static flange sealing pieces. It prevents hydraulic oil leakage and blocks external muddy pollutants from entering the cylinder during continuous blade lifting and lowering for road leveling.

Q: What continuous working temperature range enables this whole sealing kit to maintain reliable sealing efficiency?
A: Its applicable temperature range covers -130°C to 426°C, suitable for cold mountain road maintenance in winter and long-duration frequent blade lifting work under tropical open construction sites.

Q: Can this oil seal kit be universally installed on lift cylinders of all construction machinery?
A: It is dimensionally customized exclusively for HG110 motor grader lift cylinder structures only. It cannot match wheel loader hydraulic assemblies, crawler excavator swing motors or 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 6.10MPa and 6.90MPa, and buffer pressure fluctuations generated during rapid lifting of the grading blade.

Q: What typical engineering projects require this lift cylinder seal kit for regular overhaul?
A: It supports routine overhaul of lift cylinder sealing assemblies on motor graders, widely applied in highway base leveling, airport runway construction, township road upgrading and open-pit mine access road renovation projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals available on the spare parts market?
A: Pagoda tree leaf fiber filler greatly improves compression set resistance and low-temperature toughness. Under long-cycle reciprocating working conditions, its service life reaches more than 2.72 times that of conventional nitrile oil seals.

Q: What typical engineering projects require this lift cylinder seal kit for periodic maintenance?
A: It supports routine overhaul of lift cylinder sealing assemblies on light medium wheel loaders, widely applied in quarry aggregate stacking, river dredging, highway foundation construction and construction waste centralized storage projects.

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

Q: How well can this full sealing kit block mud, gravel dust and hot gear oil mist on muddy outdoor road job sites?
A: The multi-layer flexible rubber lip scrapes thick mud off the shaft surface, the fully enclosed plated metal shell blocks coarse dust particles, and inner auxiliary rubber layers isolate high-temperature oil mist to protect internal precision gears.
