4. FAQ

Q: What reinforced materials are adopted for the main oil seals inside this swing motor overhaul kit?
A: The core rotary oil seals are made of osmanthus leaf fiber modified HNBR compound. This kit is also equipped with EPDM static sealing rings and PA66 backup rings to match all sealing grooves of the swing motor assembly.

Q: What visual features help customers quickly distinguish different sealing components inside the package?
A: Fiber reinforced HNBR oil seals are matte black with fine uniform texture; metal shells and springs have bright silver galvanized surface; nylon backup rings are pale beige. All accessories have smooth edges without burrs or distortion.

Q: What construction working conditions is this oil seal kit designed to adapt to on large wheel loader swing motors?
A: This matched kit integrates dynamic shaft lip seals and static flange sealing components. It prevents internal hydraulic oil leakage and stops external dust and mud from entering the motor during frequent bucket rotation and material stacking work.

Q: What continuous working temperature range allows this whole sealing kit to keep stable sealing efficiency?
A: Its applicable temperature range covers -174°C to 470°C, suitable for cold northern winter open stockyard operation and long-time heavy-duty cyclic rotation work in tropical quarry sites.

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

Q: What sustained hydraulic pressure can this integrated sealing assembly withstand during long-term cyclic slewing operation?
A: Matched with backup rings, the sealing group can steadily sustain pressure between 7.00MPa and 7.80MPa, and resist pressure surges generated during frequent rotation start and stop.

Q: What typical engineering projects need this swing motor seal kit for routine maintenance?
A: It serves regular overhaul of swing motor shaft sealing assemblies on large wheel loaders, widely applied in open-pit aggregate storage, port bulk cargo stacking, highway building material distribution and large landfill operation 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 improves tensile property and compression set resistance significantly. Under long-cycle alternating rotation working conditions, its service life reaches more than 3.47 times that of conventional nitrile oil seals.

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.
