5. 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: What installation tips should mechanics follow during field replacement?
A: Clean and polish shaft surface to remove burrs, apply thin grease layer before pressing‑in; avoid sharp tools damaging sealing lips.

Q: What protective function does zinc‑phosphate coating provide for steel shell?
A: This surface treatment strengthens shell anti‑rust property and coating adhesion for damp, muddy construction‑site conditions.

Q: What key points should installers notice during on‑site replacement?
A: Keep shaft surface smooth and burr‑free, apply thin layer grease before pressing‑in, avoid twisting or scratching sealing lip in operation.

Q: How is its performance with commonly‑used transmission lubricants?
A: NBR material delivers stable oil resistance, maintains low swelling rate for transmission gear oil and chassis bearing grease.

Q: What suggestions for warehouse storage of unopened seal kits?
A: Store in cool dry indoor space, avoid heavy stacking pressure, sharp cuts and long‑term exposure to heat sources.

Q: How will this sealing kit interact with construction‑site lubricants?
A: Nitrile rubber keeps stable dimensional property and low‑swelling rate against transmission gear oil and conveyor bearing grease.

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.
