4. FAQ
Q: Can this oil seal work steadily on rotating shaft assemblies?
A: Yes, the specially designed sealing lip fits rotary shafts to block internal lubricant leakage.
Q: Could this oil seal kit fit drum assemblies from several similar milling machines?
A: It is built for fixed shaft and bore dimensions, please confirm size specifications before placing purchase orders.
Q: How are these seal pieces protected for overseas long‑haul logistics?
A: Every set is sealed in anti‑moisture plastic bag and packed in thick corrugated carton to resist shock and squeeze.
Q: What installation suggestions should repair technicians keep in mind?
A: Hard‑rubber pressing sleeves are recommended; avoid sharp tools to prevent cutting seal lip during fitting process.
Q: What pre‑installation work should be finished before mounting brand‑new seals?
A: Clean drum housing cavity thoroughly, check shaft surface for scratches, micro‑cracks and excessive wear traces.
Q: Are heavy‑duty external dust‑excluding wiper seals included inside this set?
A: Wiper seals are supplied, which block mud, rock dust and grit from invading final‑drive internal cavity.
Q: What harsh site conditions will reduce the service lifespan of these sealing parts?
A: Long‑time muddy construction operation, degraded gear lubricant and sustained high drive‑housing temperature will accelerate seal deterioration.
Q: What abnormal conditions indicate oil seals should be replaced?
A: Lubricant leaks out from conveyor drive shaft end, conveyor runs unevenly, periodic scraping noise occurs and drive housing produces obvious over‑heat during paving work.
Q: What risk will scratch damage bring to electrophoretic coated shell?
A: Once the coating layer is scratched off, bare steel will corrode gradually, which may lead to seal loosening and unexpected oil leakage.
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.
