5. FAQ

Q: What is the function of this floating oil seal on excavators?
A: It is installed in the travel final drive unit. It seals lubricating oil inside to ensure normal operation of gears and bearings, and isolates outside mud, dust and water to prevent internal component damage.

Q: Why choose alloy steel and anti-aging NBR for this seal?
A: Alloy steel boasts great wear resistance and structural stability against long-term friction. The upgraded NBR rubber resists aging and oil erosion, retaining good elasticity under continuous vibration and load.

Q: Could you describe its appearance and structure?
A: The alloy rings are metallic silver with finely ground sealing surfaces. The rubber components are black annular sleeves. The assembly is symmetrically paired, with neat workmanship and standard overall dimensions.

Q: Is this part compatible with original factory parts?
A: Yes. It is manufactured in accordance with OEM specifications. It can be directly installed and replaced without any secondary processing.

Q: What should be noticed during installation?
A: Clean the installation cavity thoroughly first. Do not knock or scratch the metal sealing surface. Keep rubber rings flat during installation, and check for oil leakage after assembly.

Q: How is its sealing performance in complex construction environments?
A: The dual-layer sealing structure provides excellent protection. It effectively blocks all kinds of outdoor contaminants, and keeps a good sealing state even in long-term muddy and dusty work.
