4. FAQ

Q: What materials compose this oil seal kit?
A: The sealing lip is XNBR carboxylated nitrile rubber for superior wear resistance, and outer shell is galvanized stamped‑steel equipped with high‑strength helical garter spring.

Q: Can this seal block construction‑site mud and grit from entering final drive housing?
A: Yes, the outer mud‑scraping lip can effectively scrape off mud and grit, preventing internal lubricant leakage along the rotating final drive shaft.

Q: What installation reminders should technicians follow during field replacement?
A: Polish shaft surface to clear tiny burrs and sharp spots, apply thin even grease layer before pressing‑in; avoid sharp tools damaging sealing lip working edge.

Q: What practical performance does zinc‑alloy treatment bring for steel shell?
A: This surface treatment strengthens shell surface hardness and anti‑rust property, adapting to muddy quarry and heavy‑duty earth‑moving working sites.

Q: What installation reminders should field technicians keep in mind?
A: Clean shaft surface thoroughly and remove micro burrs, apply thin uniform grease film before pressing‑in; avoid sharp tools damaging the working edge of sealing lip.

Q: What warehouse storage tips for unopened seal kits?
A: Keep in cool dry indoor zone. Avoid heavy stacking extrusion, sharp scratches and long‑time exposure to heat sources and ultraviolet rays.

Q: What practical working sign tells technicians to replace seals promptly?
