4. FAQ

Q: What modified elastomer material is adopted for the core rotary oil seals inside this circle drive motor overhaul kit?
A: The primary rotary oil seals adopt banyan leaf 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 circle drive motor assembly.

Q: What alternating rotation working conditions is this oil seal kit designed to adapt to on HG120 motor grader circle drive motors?
A: This integrated kit combines rotary shaft lip seals and static flange sealing pieces. It prevents hydraulic oil leakage and blocks external muddy pollutants from entering the motor during continuous blade rotation and road leveling operations.

Q: What continuous working temperature range enables this whole sealing kit to sustain reliable sealing capacity?
A: Its applicable temperature range covers -131°C to 427°C, suitable for cold plateau winter highway maintenance and long-duration blade rotation work under tropical open construction sites.

Q: Can this oil seal kit be universally installed on circle drive motors of all construction machinery?
A: It is dimensionally customized exclusively for HG120 motor grader circle drive motor structures only. It cannot match hydraulic assemblies of wheel loaders, swing motors of crawler excavators or hydraulic drive units of road rollers from 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 6.12MPa and 6.92MPa, and cope with pressure fluctuations generated during fast blade steering adjustment.

Q: What typical engineering projects require this circle drive motor seal kit for regular maintenance?
A: It supports routine overhaul of circle drive motor sealing assemblies on motor graders, widely applied in highway leveling, airport pavement construction, rural road reconstruction and mine access road maintenance 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: Banyan leaf fiber filler greatly improves compression recovery and abrasion resistance. Under long-cycle alternating rotation working conditions, its service life reaches more than 2.74 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 wipe tiny particles attached to the rotating shaft surface. The metal outer shell isolates coarse grit, lowering abrasive wear and slowing down the occurrence of slow hydraulic oil seepage.

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: The added plant fiber filler greatly improves compression recovery and anti-fatigue property. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.46 times that of conventional nitrile oil seals.
