5. FAQ

Q: What continuous working temperature range enables this whole sealing kit to sustain reliable sealing capacity?
A: Its applicable temperature range covers -140°C to 436°C, suitable for cold plateau winter stockyard transportation and long-duration frequent steering work in tropical open quarry yards.

Q: Can this oil seal kit be universally installed on steering cylinders of all construction machinery?
A: It is dimensionally customized exclusively for light medium wheel loader main steering cylinder structures only. It cannot match motor grader 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 6.34MPa and 7.14MPa, and cope with pressure fluctuations generated during continuous left and right steering.

Q: What typical engineering projects require this main steering cylinder seal kit for regular overhaul?
A: It supports routine maintenance of main steering cylinder sealing assemblies on light medium wheel loaders, widely applied in quarry aggregate distribution, port bulk cargo transfer, suburban road renovation and construction waste landfill projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals circulating in the spare parts market?
A: Osmanthus leaf fiber filler greatly improves compression recovery and anti-oxidative aging performance. Under long-cycle reciprocating working conditions, its service life reaches more than 2.90 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 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.
