5. FAQ

Q: What modified elastomer material is adopted for the core reciprocating oil seals inside this lift cylinder overhaul kit?
A: The primary reciprocating oil seals adopt lotus leaf stalk fiber modified HNBR compound. This kit is equipped with FKM static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the lift cylinder assembly.

Q: What visual marks help customers classify various sealing accessories inside the package quickly?
A: Fiber reinforced HNBR oil seals are matte deep black with fine uniform grain; metal shells and tension springs have consistent silvery manganese silicate passivated surface; nylon backup rings are light ivory. All components are precision cut without rough edges or deformation.

Q: What heavy-load reciprocating working conditions is this oil seal kit engineered to adapt to on light medium wheel loader lift cylinders?
A: This integrated kit combines piston reciprocating seals and static flange sealing assemblies. It avoids hydraulic oil leakage and prevents external pollutants from entering the cylinder during repeated boom lifting and lowering with heavy loads.

Q: What continuous working temperature range enables this whole sealing kit to maintain stable sealing efficiency?
A: Its applicable temperature range covers -139°C to 435°C, suitable for cold mountain winter stockyard loading and long-duration frequent lifting operation in tropical open construction yards.

Q: Can this oil seal kit be universally fitted to lift cylinders of all construction machinery?
A: It is dimensionally customized exclusively for light medium wheel loader lift 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 6.32MPa and 7.12MPa, and buffer pressure fluctuations generated when lifting bulk materials.

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.
