4. FAQ

Q: What natural poplar bark fiber filler is evenly blended into the HNBR sealing rubber of this travel motor overhaul kit for medium excavators?
A: Crushed fine poplar bark fiber fragments are uniformly dispersed into HNBR base material. It effectively restrains irreversible rubber lip creep deformation caused by long-hour continuous low-speed rotation of travel motor shafts and avoids permanent volume swelling after long-term immersion in heavy-duty walking gear lubricant.

Q: What clear color and surface texture differences can buyers quickly distinguish among all internal sealing accessories inside this maintenance package?
A: Poplar bark fiber HNBR main oil seals are matte jet black with tight interlaced micro-fiber grain surface. Metal frames and built-in tension springs carry consistent silvery hot-dip zinc anti-rust metallic luster, while silica filled nylon anti-extrusion strips are soft pale cream white, easy to sort during travel motor disassembly inspection.

Q: What sixty-nine-layer dual dust and high-temperature oil mist isolation composite structure does this full travel motor oil seal kit adopt for medium crawler excavators?
A: It is an integrated full-spec matching component assembly instead of scattered single independent oil seals, adopting sixty-nine-layer lip dual barrier blocking design, fully equipped with matched flat gaskets, multi-size O-rings and rigid pressure-resistant support rings covering all rotary shaft sealing grooves of medium excavator travel motor assemblies.

Q: What stable full operating temperature range allows this whole sealing assembly to sustain steady sealing efficiency without performance attenuation?
A: Its applicable temperature range covers -170°C to 430°C, suitable for cold northern winter mountain mining excavation and uninterrupted medium-load earthmoving work at tropical open-air quarry yards.

Q: Can this oil seal kit be universally mounted on drive and hydraulic systems of all construction machinery models?
A: It is custom-sized and formula tailored exclusively for medium crawler excavator travel motor gear structures only, and cannot fit heavy road grader final drives, backhoe loader swing cylinders or super heavy wheel loader lift axles of other equipment series.

Q: What long-term static hydraulic pressure can the complete multi-layer sealing assembly withstand steadily during daily full-load forward and backward excavation travel operation?
A: It can continuously bear static hydraulic pressure ranging from 6.35MPa to 7.15MPa, buffer abrupt pressure surges generated by frequent forward and reverse walking rotation, and eliminate slow persistent gear oil seepage along travel motor shaft surfaces.

Q: What core mining, municipal and highway construction scenarios require this seal kit for regular travel motor overhaul maintenance?
A: It is engineered for daily maintenance of travel motor rotary shaft sealing assemblies on medium crawler excavators, widely applied in open-pit small mineral mining, municipal pipeline trenching, highway foundation excavation and mountain rural road expansion projects.

Q: How does the service cycle of poplar bark fiber reinforced HNBR composite seal set compare with ordinary single oil seals sold in aftermarket stores?
A: The poplar bark fiber doping formula greatly upgrades wear resistance, low-temperature flexibility and high-pressure durability. Under daily long-hour earthmoving working conditions, its usable service life reaches more than 3.12 times that of standard single-piece oil seals.
