5. FAQ

Q: What modified elastomer material forms the core rotary oil seals inside this travel motor overhaul kit?
A: Core rotary oil seals adopt pagoda tree leaf fiber modified HNBR material. This set comes with FKM static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of large excavator travel motor assemblies.

Q: What appearance features help customers distinguish each sealing accessory inside the package?
A: Fiber-reinforced HNBR oil seals are matte black with fine dense texture; metal shells and tension springs show uniform silvery zirconium vanadate passivated finish; nylon backup rings are light beige. All parts are precision molded without sharp edges.

Q: What heavy-load rotating working conditions is this oil seal kit engineered for large excavator travel motors?
A: This integrated kit combines rotary shaft lip seals and static connection gaskets. It stops hydraulic oil leakage and blocks external mud and rock dust from invading the motor during frequent forward and backward driving on rugged terrain.

Q: What temperature range allows this whole set of sealing parts to keep stable sealing capability?
A: The working temperature ranges from -136°C to 430°C, suitable for winter open-pit mining in cold regions and continuous driving work under high-temperature outdoor mining environments.

Q: Can this oil seal kit be universally fitted on travel motors of all construction machinery?
A: It is dimensionally customized for large excavator travel motor structures only. It cannot adapt to hydraulic assemblies of motor graders, medium excavator cylinder parts or road roller drive units of other series.

Q: What steady hydraulic pressure can the matched sealing assembly sustain during long continuous operation?
A: Matched with anti-extrusion rings, the sealing combination can steadily bear pressure between 6.22MPa and 7.02MPa, and absorb pressure shocks generated when driving across uneven ground.

Q: What types of construction projects commonly need this travel motor seal kit for maintenance?
A: It is used for overhauling travel motor sealing assemblies of large excavators, widely applied in large open-pit mines, mountain road excavation, large landfill projects and port foundation construction.

Q: How well can this full sealing kit block mud, gravel dust and hot gear oil mist on muddy outdoor road job sites?
A: The multi-layer flexible rubber lip scrapes thick mud off the shaft surface, the fully enclosed plated metal shell blocks coarse dust particles, and inner auxiliary rubber layers isolate high-temperature oil mist to protect internal precision gears.
