5. FAQ

Q: What modified elastomer raw material is adopted for the core rotary oil seals inside this drive gearbox overhaul kit?
A: The primary rotary oil seals adopt mulberry leaf fiber modified HNBR compound. This kit is equipped with EPDM static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the drive gearbox assembly.

Q: What visual cues help buyers quickly distinguish all sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are matte jet black with fine uniform grain; metal shells and tension springs have consistent silvery titanium phosphate passivated surface; nylon backup rings are light beige. All accessories are precision trimmed without burrs or surface warpage.
Q: What alternating rotation working conditions is this oil seal kit designed to adapt to on HG130 motor grader drive gearboxes?
A: This integrated kit combines rotary shaft lip seals and static flange sealing pieces. It prevents gear oil leakage and blocks external muddy pollutants from entering the gearbox during road leveling, turning and low-speed travelling operations.

Q: What continuous working temperature range enables this whole sealing kit to sustain reliable sealing efficiency?
A: Its applicable temperature range covers -132°C to 428°C, suitable for cold mountain road maintenance in winter and long-duration continuous grading work under high-temperature open-air construction sites.

Q: Can this oil seal kit be universally installed on drive gearboxes of all construction machinery?
A: It is dimensionally customized exclusively for HG130 motor grader drive gearbox 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 6.14MPa and 6.94MPa, and resist pressure fluctuations generated during sharp turning and load changes.

Q: What typical engineering projects require this drive gearbox seal kit for regular overhaul?
A: It supports routine maintenance of drive gearbox sealing assemblies on motor graders, widely applied in highway leveling, municipal road reconstruction, airport ground construction and 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: Mulberry leaf fiber filler greatly improves compression set resistance and anti-fatigue performance. Under long-cycle alternating rotation working conditions, its service life reaches more than 2.76 times that of conventional nitrile oil seals.

Q: How will these oil seals perform under long-term outdoor muddy and dusty road construction environments?
A: The precision sealing lip can scrape sediment adhered to the rotating shaft surface. The metal outer shell isolates coarse grit, lowering abrasive wear and slowing down the occurrence of slow gear oil seepage.

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.
