4. FAQ

Q: What natural palm frond fiber filler is evenly blended into the HNBR sealing rubber of this pilot gear motor overhaul kit?
A: Ultra-fine crushed palm frond fiber fragments are uniformly fused into HNBR base raw material. It effectively suppresses gradual surface fatigue abrasion caused by long-term variable-speed rotation of pilot motor shafts and prevents permanent rubber expansion after continuous contact with low-pressure pilot hydraulic medium.

Q: What distinct color and surface texture differences can buyers quickly distinguish among all internal sealing accessories inside this maintenance package?
A: Palm frond fiber HNBR main oil seals are matte jet black with fine compact interwoven micro-fiber grain surface. Metal frames and built-in tension springs carry uniform silvery tin-aluminum anti-corrosion metallic luster, while wollastonite filled nylon anti-extrusion strips are soft pale off-white, easy to sort during pilot gear motor disassembly inspection.

Q: What ninety-layer dual dust and high-temperature oil mist isolation composite structure does this full pilot gear motor oil seal kit adopt for ultra large crawler excavators?
A: It is an integrated full-spec matched component assembly instead of scattered single independent oil seals, adopting ninety-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 excavator pilot gear motor assemblies.

Q: What stable continuous working temperature range allows this complete sealing assembly to maintain reliable sealing efficiency without performance attenuation?
A: Its applicable temperature range covers -169°C to 458°C, suitable for cold alpine winter large-scale infrastructure construction and uninterrupted ultra-heavy excavation work at tropical open-air mining yards.

Q: Can this oil seal kit be universally mounted on hydraulic and drive systems of all construction machinery models?
A: It is custom-sized and formula tailored exclusively for ultra large crawler excavator pilot gear motor structures only, and cannot fit heavy road grader final drives, backhoe loader drive axles or medium wheel loader hydraulic cylinders of other equipment series.

Q: What sustained static hydraulic pressure can the multi-layer composite sealing assembly withstand steadily during daily frequent manipulator operation?
A: It can continuously bear static hydraulic pressure ranging from 6.78MPa to 7.59MPa, buffer periodic pressure fluctuations generated by frequent joystick operation, and eliminate slow persistent hydraulic oil seepage along pilot motor shaft surfaces.

Q: What core open-pit mining, port construction and water conservancy projects require this seal kit for regular pilot gear motor overhaul maintenance?
A: It is engineered for daily maintenance of pilot gear motor rotary shaft sealing assemblies on ultra large crawler excavators, widely applied in super large open-pit mineral mining, port land reclamation, river regulation and coastal breakwater construction projects.

Q: What sustained static hydraulic pressure can the multi-layer composite sealing assembly withstand steadily during daily ultra-heavy cyclic slewing operation?
A: It can continuously bear static hydraulic pressure ranging from 6.68MPa to 7.49MPa, buffer abrupt pressure surges generated by frequent slewing startup and load switching, and eliminate slow persistent gear oil seepage along secondary swing motor shaft surfaces.

Q: How does the service cycle of sisal stalk fiber reinforced HNBR composite seal set compare with ordinary single oil seals sold in aftermarket stores?
A: The sisal stalk fiber doping formula greatly improves compression recovery, low-temperature elasticity and high-pressure durability. Under daily continuous heavy compound excavation working conditions, its usable service life reaches more than 3.24 times that of standard single-piece oil seals.
