4. FAQ

Q: What modified elastomer material is adopted for the core rotary oil seals inside this swing motor overhaul kit?
A: The main rotary oil seals use locust leaf fiber modified HNBR compound. This set is equipped with NBR static O-rings and PA66 backup rings to match all dynamic and static sealing grooves of the swing motor assembly.

Q: What visual features help customers quickly sort all sealing parts inside the package?
A: Fiber-reinforced HNBR oil seals are matte dark black with delicate uniform texture; metal shells and tension springs feature consistent silvery chromium vanadate passivated finish; nylon backup rings are light cream. All components are precisely molded without burrs or distortion.

Q: What alternating rotation working conditions is this oil seal kit designed to handle on medium excavator swing motors?
A: This integrated kit includes rotary shaft lip seals and static flange gaskets. It stops hydraulic oil leakage and stops external sediment from entering the motor during frequent bucket excavation and machine slewing on job sites.

Q: What continuous working temperature range allows this whole sealing kit to maintain stable sealing performance?
A: Its applicable temperature range is -142°C to 436°C, suitable for open-pit excavation in cold mountain winters and long-duration cyclic slewing under high-temperature tropical construction environments.

Q: Can this oil seal kit be universally mounted on swing motors of all construction equipment?
A: It is dimensionally customized only for medium excavator swing motor structures. It cannot fit hydraulic assemblies of motor graders, travel motors of wheel loaders or vibratory units of road rollers of other equipment series.

Q: What lasting hydraulic pressure can this matched sealing assembly endure during long-cycle operation?
A: Matched with backup rings, the sealing group can steadily bear pressure ranging from 6.36MPa to 7.16MPa, and absorb pressure fluctuations produced during fast left and right slewing.

Q: What typical construction projects require this swing motor seal kit for periodic maintenance?
A: It is used for routine overhaul of swing motor sealing assemblies on medium excavators, widely used in open pit mining, river dredging, residential foundation construction and highway expansion projects.

Q: How will these oil seals perform under long-term outdoor muddy and dusty road construction environments?
A: The precision sealing lip can wipe sediment adhered to the piston rod surface. The metal outer shell isolates coarse grit, lowering abrasive wear and slowing down the occurrence of slow steering hydraulic fluid seepage.

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.
