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 benefits does zinc‑alloy treatment bring for steel shell?
A: This surface treatment improves shell surface hardness and rust‑resistant capacity, adapting to open‑air road construction sites with sand, dust and moisture.

Q: What early‑stage abnormal signs remind maintenance staff to replace oil seals?
A: Watch for gradual gear oil seepage at shaft end and intermittent low‑pitch humming noise when motor grader turns or travels over rough ground.

A: Please provide accurate shaft diameter and housing bore dimension data, we can deliver practical matching guidance for large‑volume procurement and stock preparation.

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?
