5. FAQ

Q: What mineral whisker composite filler is blended into the core sealing rubber of this bulldozer overhaul set?
A: Zirconium-aluminum silicate whiskers are evenly mixed into modified NBR base rubber. It greatly slows rubber creep deformation generated by long-term bidirectional rotation of final drive shafts and avoids swelling damage after long contact with heavy gear lubricant.

Q: What visual color and texture differences can buyers quickly tell apart among all internal kit accessories?
A: All rubber sealing pieces are matte dark grey black with delicate fibrous texture on the surface. Metal frames and built-in springs carry uniform silver electroplated luster, while nylon support rings are soft pale beige for easy classification during assembly.

Q: What multi-layer dual isolation structure does this full final drive seal kit adopt for light crawler bulldozers?
A: It is an integrated matching accessory set instead of single separate seals, adopting twenty-four lip dual dust and high-temperature oil mist blocking design, equipped with matched flat gaskets, multi-size O-rings and pressure-resistant back-up rings covering all rotary shaft sealing positions of final drives.

Q: What stable operating temperature range can this whole sealing assembly adapt to?
A: Its applicable temperature range is -161°C to 380°C, suitable for cold mountain winter earthmoving and continuous light-load pushing work at sand yards and rural road construction sites.

Q: Can this sealing set be matched to all types of construction machinery universally?
A: It is specially designed only for light crawler bulldozer final drive gear assemblies, and cannot be installed on wheel loaders, large excavators or road graders of other models.

Q: What steady long-term hydraulic pressure can this sealing assembly withstand during daily operation?
A: It can continuously bear static hydraulic pressure of 4.85MPa to 6.55MPa, and buffer sudden pressure spikes from startup, emergency stop and load switching to prevent slow gear oil leakage.
