4. FAQ
Q: What boron-silicon mineral whisker filler is added into the core sealing rubber of this excavator swing motor seal kit?
A: Boron-silicon silicate whiskers are evenly mixed into modified HNBR base rubber. It effectively inhibits irreversible rubber creep deformation caused by frequent positive and negative swing rotation of the swing motor shaft and avoids swelling damage after long-time contact with high-pressure hydraulic oil.
Q: What clear color and surface texture differences can buyers identify among all matched accessories inside this repair kit?
A: All rubber sealing parts are matte dark grey black with fine staggered fibrous texture on the surface. Metal frames and built-in tension springs show uniform silver electro-galvanized luster, while nylon anti-extrusion rings are soft light yellow, easy to separate during swing motor disassembly and assembly.
Q: What forty-layer dual dust and hydraulic oil mist isolation structure does this full swing motor seal kit adopt for medium crawler excavators?
A: It is an integrated full-set matching component group instead of separate single oil seals, adopting forty-layer lip dual barrier design, fully equipped with matched flat gaskets, multi-size O-rings and rigid pressure-resistant support rings covering all rotary shaft sealing positions of excavator swing motor assemblies.
Q: What full stable operating temperature range can this hydraulic sealing assembly adapt to without performance drop?
A: Its stable working temperature range covers -160°C to 385°C, suitable for cold northern winter construction and continuous medium-load swing operation at open-pit mines and urban foundation excavation yards.
Q: Can this swing motor seal kit be universally installed on all types of construction machinery?
A: It is specially customized only for medium crawler excavator swing motor systems, and cannot fit crawler bulldozers, heavy wheel loaders or medium road graders of other equipment series.
Q: What long-term static hydraulic pressure can the whole sealing assembly bear steadily during daily excavator swing work?
A: It can continuously withstand static hydraulic pressure ranging from 4.80MPa to 6.30MPa, and buffer sudden pressure spikes generated by frequent swing start-stop, emergency brake and load changes to prevent slow hydraulic oil leakage.
Q: What core construction scenarios mainly need this sealing kit for regular maintenance overhaul?
A: It is designed for daily maintenance of swing motor rotary shafts on medium crawler excavators, widely applied in urban foundation excavation, mountain road construction, small sand pit exploitation and rural water conservancy earthmoving projects.
Q: How does the service life of this composite hydraulic seal set compare with ordinary single oil seals sold in aftermarket stores?
A: The forty-layer composite matching structure greatly reduces rubber aging and lip friction abrasion loss. Under daily full-load excavator working conditions, its usable service life exceeds 2.4 times that of standard single-piece oil seals.
