4. FAQ

Q: What natural ramie stalk fiber filler is evenly mixed into the HNBR sealing rubber of this central swivel joint overhaul kit?
A: Purified fine ramie stalk fiber filaments are uniformly incorporated into HNBR base material. It alleviates persistent surface abrasion caused by uninterrupted low-speed rotation of swivel joint shafts and prevents irreversible expansion after long contact with multi-way hydraulic transfer fluid.

Q: What visual color and texture differences can buyers quickly recognize among all sealing accessories inside this overhaul set?
A: Ramie stalk 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 pyrophyllite nylon back-up rings are pale ivory white, convenient for classification during swivel joint disassembly.

Q: What seventy-nine-layer dual dust and high-temperature oil mist blocking composite structure does this full central swivel joint oil seal kit adopt for super large crawler excavators?
A: It is an integrated matched component assembly rather than separate individual seals, adopting seventy-nine-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 central swivel joint 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 447°C, suitable for frigid mountain winter infrastructure construction and continuous heavy-load earthmoving work at high-temperature open-air mining 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 super large crawler excavator central swivel joint 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 stable full operating temperature range allows this complete sealing assembly to sustain steady sealing efficiency without performance attenuation?
A: Its applicable temperature range covers -176°C to 445°C, suitable for cold plateau winter mining construction and uninterrupted heavy-load slewing digging 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 large crawler excavator swing reduction gear 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 long-term static hydraulic pressure can the multi-layer composite sealing assembly withstand steadily during daily frequent slewing excavation operation?
A: It can continuously bear static hydraulic pressure ranging from 6.52MPa to 7.33MPa, buffer abrupt pressure surges generated by frequent left and right slewing movements, and eliminate slow persistent gear oil seepage along swing reduction gear shaft surfaces.

Q: What core mining, water conservancy and infrastructure construction scenarios require this seal kit for regular swing reduction gear overhaul maintenance?
A: It is engineered for daily maintenance of swing reduction gear rotary shaft sealing assemblies on large crawler excavators, widely applied in open-pit quarry mining, river channel dredging, large industrial zone foundation excavation and mountain highway widening projects.
