4. FAQ

Q: What natural rush fiber filler is evenly blended into the HNBR sealing rubber of this secondary swing motor overhaul kit?
A: Purified fine rush fiber fragments are uniformly fused into HNBR base raw material. It effectively suppresses irreversible lip fatigue deformation caused by long-period frequent clockwise and counter-clockwise rotation of secondary swing motor shafts and prevents permanent volume expansion after long contact with slewing gear lubricant.

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

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

Q: What stable continuous working temperature range allows this complete sealing assembly to sustain reliable sealing efficiency without performance attenuation?
A: Its applicable temperature range covers -175°C to 453°C, suitable for cold alpine region large-scale mining construction and uninterrupted ultra-heavy slewing excavation work at tropical open-air quarry yards.

Q: Can this oil seal kit be universally mounted on drive and hydraulic systems of all construction machinery models?
A: It is custom-sized and formula tailored exclusively for ultra large crawler excavator secondary swing 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 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.
