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: What lubricating fluid suits the working condition of these sealing components?
A: It performs steadily with standard axle gear oil widely used for wheel excavator wheel‑end assemblies.

Q: Are outer mud‑proof wiper seals contained in this whole repair set?
A: Wiper seals are supplied, which block muddy soil, sand and gravel particles from entering hub inner cavity.

Q: What site conditions will speed up performance degradation of these seals?
A: Frequent travelling on muddy ground, contaminated gear lubricant and sustained high hub temperature will shorten service time.

Q: Does this overhaul kit contain all sealing consumables for full conveyor maintenance?
A: Yes. It includes main conveyor drive shaft oil seal, multi‑size O‑rings, anti‑extrusion backup rings and thin sealing gaskets for one‑time complete conveyor assembly repair.

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.
