4. FAQ

Q: What special reinforced formula is used for the primary oil seals inside this swing cylinder overhaul kit?
A: The main reciprocating oil seals are manufactured from osmanthus twig fiber modified HNBR material. The kit is equipped with NBR static sealing rings and PA66 backup rings to fit all sealing grooves of the swing cylinder assembly.

Q: What visual features help buyers distinguish different sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are dark black with smooth matte finish; metal shells and tension springs have uniform silvery bright dipped surface; nylon backup rings are pale ivory. All components are neatly trimmed without burrs or deformation.

Q: What variable load working conditions is this oil seal kit designed to adapt to on large wheel loader swing cylinders?
A: This integrated kit combines piston reciprocating seals and static flange sealing pieces. It prevents hydraulic oil leakage inside the cylinder and stops external silt from entering the cylinder barrel during frequent bucket lifting and swinging movements.

Q: What continuous working temperature range allows this whole sealing kit to maintain stable sealing capacity?
A: Its applicable temperature range covers -164°C to 460°C, suitable for cold highland winter stockyard loading and long-duration cyclic bucket operation in tropical open quarry yards.

Q: Can this oil seal kit be universally installed on hydraulic cylinders of all construction machinery?
A: It is dimensionally customized exclusively for large wheel loader swing cylinder structures only. It cannot match motor grader hydraulic assemblies, crawler excavator hydraulic motors or medium roller drive units of other equipment series.

Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-term cyclic operation?
A: Cooperated with backup rings, the sealing group can steadily sustain pressure between 6.80MPa and 7.60MPa, and cope with pressure fluctuations generated during heavy bucket load switching.

Q: What typical engineering projects require this swing cylinder seal kit for regular maintenance?
A: It supports routine overhaul of swing cylinder sealing assemblies on large wheel loaders, widely applied in quarry aggregate stacking, port bulk cargo transfer, highway base material transportation and construction waste landfill projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals on the spare parts market?
A: The added plant fiber filler greatly improves compression recovery and anti-fatigue property. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.46 times that of conventional nitrile oil seals.
