5. FAQ

Q: What palm plant fiber filler is evenly compounded into the HNBR sealing rubber of this heavy grader final drive overhaul kit?
A: Refined short palm fiber fragments are uniformly fused into HNBR base material. It effectively suppresses irreversible rubber creep deformation triggered by long-hour low-speed continuous rotation of final drive shafts and avoids permanent volume swelling after prolonged contact with thick heavy-duty transmission gear lubricant.

Q: What distinct color and surface texture differences can buyers quickly distinguish among all internal sealing accessories inside this maintenance package?
A: Palm fiber HNBR main oil seals are matte charcoal black with tight compact micro-fiber interwoven grain surface. Metal frames and built-in tension springs feature consistent soft silvery tin-zinc anti-corrosion metallic luster, while nylon anti-extrusion strips are pale ivory white, easy to separate during final drive disassembly inspection.

Q: What fifty-nine-layer dual dust and high-temperature oil mist isolation composite structure does this full final drive oil seal kit adopt for heavy road graders?
A: It is an integrated full-spec matching component assembly instead of scattered single independent oil seals, adopting fifty-nine-layer lip dual barrier blocking design, fully equipped with matched flat gaskets, multi-size O-rings and rigid pressure-resistant support rings covering all rotary shaft sealing grooves of heavy grader final drive assemblies.

Q: What stable full operating temperature range allows this whole sealing assembly to sustain steady sealing efficiency without performance loss?
A: Its applicable temperature range covers -174°C to 438°C, suitable for frigid northern winter highway base construction and uninterrupted heavy road surface trimming work under high-temperature open-air road yards.

Q: Can this oil seal kit be universally installed on transmission drive systems of all construction machinery models?
A: It is custom-sized and formula tailored exclusively for heavy road grader final drive gear systems only, and cannot fit super heavy wheel loader middle drive axles, medium excavator swing motors or backhoe loader bucket cylinders of other equipment series.

Q: What long-term static hydraulic pressure can the complete sealing assembly withstand steadily during daily full-load road grading operation?
A: It can continuously bear static hydraulic pressure ranging from 6.22MPa to 7.12MPa, buffer abrupt pressure surges generated by frequent forward and reverse low-speed grading rotation, and eliminate slow persistent gear oil seepage along final drive shaft surfaces.

Q: What core municipal and large highway construction scenarios require this seal kit for regular final drive overhaul maintenance?
A: It is engineered for daily maintenance of final drive rotary shaft sealing assemblies on heavy road graders, widely applied in municipal road reconstruction, airport apron leveling, provincial highway pavement finishing and mountain town road expansion projects.
