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 color options do these sealing accessories have?
A: The main shaft seal is black rubber with dark grey metal shell, POM backup rings are off‑white, and matched O‑rings are deep black.

Q: What type of lubricating fluid works best with these sealing assemblies?
A: It performs well with standard tractor transmission oil and common agricultural gear lubricants.

Q: Are external dirt‑excluding wiper seals included within this whole kit?
A: Wiper seals are supplied, which block farm soil, crop debris and fine dust from entering shaft housing.

Q: What operating conditions will shorten the usable life of these sealing pieces?
A: Frequent on‑farm start‑stop cycles, contaminated lubricant and sustained high operating temperature will accelerate seal deterioration.

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.
