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: What practical advantages does Redicoat treatment bring for steel shell?
A: This coating fills minor bore imperfections and improves rust‑resistant performance, adapting to wet muddy mine and quarry operating sites.

Q: Can this seal keep construction dust and muddy splashes away from motor housing?
A: Yes, the outer dust‑scraping lip can block grit and muddy water effectively, preventing internal lubricant leakage along rotating swing motor shaft.

Q: What early‑warning symptoms tell us seals need to be replaced?
A: Watch for slow gear oil seepage at shaft end and intermittent low‑pitch tapping noise when wheel dozer travels over uneven rough ground.

Q: What practical performance advantages does Redicoat treatment bring for steel shell?
A: This special surface treatment improves shell fitting performance and rust‑proof capacity, adapting to dusty quarry sites with mud and alternating humidity conditions.

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?
A: Gradual grease seepage mixed with street sand and dust particles around brush‑drive housing indicates seal abrasion and gradual aging performance drop.
