5. FAQ

Q: What stable full working temperature range can this whole sealing assembly keep steady sealing performance without decline?
A: Its applicable temperature range covers -173°C to 444°C, suitable for cold plateau winter highway paving and non-stop super heavy pavement trimming work at tropical open-air road construction yards.

Q: Can this oil seal kit be installed universally on transmission drive systems of all construction machinery models?
A: It is customized only for super heavy road grader front and rear combined final drive gear structures, and cannot fit wheel loader axles, excavator swing motors or backhoe loader hydraulic cylinders of other machine series.

Q: What steady static hydraulic pressure can the complete multi-layer sealing assembly bear during daily full-load grading forward and reverse rotation?
A: It can continuously bear static hydraulic pressure from 6.30MPa to 7.20MPa, buffer sudden pressure surges from frequent steering and leveling actions, and eliminate slow gear oil seepage on drive shaft surfaces.

Q: What core construction projects need this seal kit for regular combined final drive overhaul maintenance?
A: It is designed for daily maintenance of front and rear final drive rotary shafts on super heavy road graders, widely applied in airport runway leveling, national highway reconstruction, municipal road base compaction and mountain rural road expansion projects.

Q: How does the service life of cotton stalk fiber reinforced HNBR composite seals compare with ordinary single oil seals sold in aftermarket stores?
A: The cotton stalk fiber composite formula greatly improves compression recovery and low-temperature flexibility. Under daily full-load heavy road grading working conditions, its service life reaches more than 3.12 times that of standard single-piece oil seals.

Q: Can this double barrier sealing assembly effectively block mud, gravel dust and suspended hot gear oil mist on long-time muddy outdoor road construction sites?
A: Yes. The sixty-three-layer elastic rubber lip scrapes thick mud from the shaft surface, fully enclosed aluminum plated metal shell blocks coarse dust particles, and inner auxiliary rubber layers isolate high-temperature oil mist to protect internal precision gear components.

Q: Does this dual-barrier sealing assembly deliver reliable anti-mud and dust isolation performance in long-time muddy outdoor road construction environments?
A: Yes. The sixty-layer elastic rubber lip cooperates with fully enclosed nickel-zinc plated metal frames to form double isolation barriers, blocking road mud, coarse gravel and suspended high-temperature gear oil mist from invading the front final drive’s internal precision gear components.
