4. FAQ

Q: What natural camphor bark fiber filler is evenly blended into the HNBR sealing rubber of this auxiliary brake pump overhaul kit?
A: Purified fine camphor bark fiber fragments are uniformly incorporated into HNBR base raw material. It effectively reduces surface fatigue abrasion caused by irregular intermittent rotation and prevents irreversible expansion after long contact with auxiliary brake hydraulic medium.

Q: What visual color and texture differences can buyers quickly recognize among all sealing accessories inside this overhaul package?
A: Camphor bark fiber HNBR main rotary seals are matte deep black with dense interwoven micro-fiber texture. Plated metal housings and tension springs show uniform silvery zinc-tin metallic luster, while sepiolite filled nylon back-up rings are pale beige, convenient for classification during pump disassembly work.

Q: What ninety-three-layer dual dust and high-temperature oil mist blocking composite structure does this full auxiliary brake pump oil seal kit adopt for ultra large crawler excavators?
A: It is an integrated matched component assembly rather than separate individual seals, adopting ninety-three-layer lip dual barrier design, equipped with matched flat gaskets, multi-size O-rings and pressure-resistant support rings covering all rotary shaft sealing grooves of excavator auxiliary brake pump assemblies.

Q: What working temperature range enables this complete sealing assembly to operate steadily without declining sealing performance?
A: Its applicable temperature range covers -170°C to 461°C, suitable for frigid mountain winter mining construction and continuous heavy-duty excavation work at high-temperature open-air quarry yards.

Q: Can this oil seal kit be mounted universally on drive and hydraulic systems of all construction machinery?
A: It is dimensionally and formula customized only for ultra large crawler excavator auxiliary brake pump structures, and cannot be installed on backhoe loader drive axles, road grader final drives or wheel loader hydraulic cylinders of other machine series.

Q: What continuous static hydraulic pressure can the multi-layer matched sealing assembly withstand during daily frequent emergency braking operations?
A: It can steadily sustain static hydraulic pressure ranging from 6.84MPa to 7.65MPa, absorb sudden pressure spikes brought by urgent brake triggering, and stop slow hydraulic oil seepage along auxiliary brake pump shaft surfaces.

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.
