5. FAQ

Q: What natural ramie fiber material is added into the HNBR rubber of this rear final drive maintenance kit?
A: Fine refined ramie fiber filaments are evenly blended into HNBR base material. It effectively reduces long-term fatigue abrasion on the sealing lip caused by slow continuous rotation of final drive shafts and prevents permanent expansion after long contact with heavy-duty transmission gear oil.

Q: What visual color and texture differences can buyers easily tell apart among all sealing parts inside this package?
A: Ramie fiber HNBR main rotary seals are matte dark black with fine woven fiber grain. Plated metal frames and springs carry uniform silvery aluminum-zinc luster, while alumina nylon back-up rings are soft cream white, easy to sort during drive disassembly inspection.

Q: What multi-layer dual protection structure does this full rear final drive oil seal kit adopt for heavy road graders?
A: It is an all-in-one matched assembly instead of separate single seals, adopting sixty-one-layer lip dual dust and oil mist barrier design, complete with matched gaskets, multi-size O-rings and pressure-resistant support rings matching all sealing grooves of grader rear final drive units.

Q: What temperature range can this full sealing assembly stably work within without losing sealing performance?
A: Its working temperature range covers -170°C to 440°C, suitable for cold plateau winter highway construction and nonstop long-time pavement trimming under high-temperature open-air construction yards.

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

Q: What steady static hydraulic pressure can the matched multi-layer seal set bear during daily full-load grading work?
A: It can sustain static hydraulic pressure from 6.26MPa to 7.16MPa, buffer sudden pressure spikes from frequent forward and reverse grading rotation, and eliminate slow gear oil seepage along the rear drive shaft surface.

Q: What main construction projects need this seal kit for regular rear final drive overhaul?
A: It is designed for routine maintenance of rear final drive rotary shafts on heavy road graders, widely used in national highway reconstruction, municipal road base compaction, large logistics park ground leveling and mountain rural road widening projects.

Q: How does the service lifespan of ramie fiber reinforced HNBR seals compare with standard single oil seals sold in the market?
A: The ramie fiber composite formula greatly improves compression recovery and anti-abrasion ability. Under daily full-load road grading working conditions, its service life reaches 3.11 times that of ordinary single-piece oil seals.

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.
