4. FAQ

Q: What visual features help customers quickly distinguish different sealing accessories inside the package?
A: Steel composite gaskets are silver gray with matte graphite surface; fiber gaskets are light tan; rubber washers are solid black; adjusting shims are bright silver metal sheets. All components are pre-cut following original housing contour standards.

Q: What sealing challenges is this gasket kit developed to solve for large crawler excavator swing device assemblies?
A: It focuses on static sealing of split housing flanges and end covers of swing devices. Multi-material matching adapts to continuous slewing vibration and ambient temperature changes to prevent gear oil leakage on joint surfaces.

Q: What continuous working temperature range enables this whole gasket kit to maintain stable sealing performance?
A: Its applicable temperature range covers -166°C to 448°C, suitable for cold northern winter open-pit mining and continuous heavy-duty slewing work in tropical stone quarry sites.

Q: Can this gasket kit be universally used for slewing assembly maintenance of all construction machinery?
A: It is dimensionally customized exclusively for large crawler excavator swing device housing structures only. It cannot fit road grader transmission housings, wheel loader axles or medium excavator hydraulic pump assemblies of other machine series.

Q: What static working pressure can these composite gaskets withstand during long-term cyclic slewing operation?
A: The matched assembly can steadily sustain static pressure ranging from 6.55MPa to 7.35MPa. It can keep tight sealing even if slight housing deformation occurs under frequent rotation impact loads.

Q: What typical large-scale engineering projects need this swing device gasket kit for regular overhaul work?
A: It is designed for routine maintenance of swing device housing sealing assemblies on large crawler excavators, widely adopted in large open-pit mineral mining, coastal land reclamation, highway tunnel construction and river regulation projects.

Q: How does the service life of these composite gaskets compare with ordinary single-layer fiber paper gaskets available on the spare parts market?
A: The magnolia leaf fiber reinforced composite structure greatly improves creep resistance and oil corrosion resistance. Under long-term cyclic vibration working conditions, its service life reaches more than 3.22 times that of standard fiber paper gaskets.
