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 harsh working environment can this seal kit cope with?
A: It can resist heavy hoisting torque shock, outdoor rain splash, wind‑blown construction dust and large temperature difference during long‑time lifting operations.

Q: Does this overhaul kit contain all sealing spare parts for full gearbox maintenance?
A: Yes, it includes main slew shaft oil seal, multi‑dimension O‑rings, anti‑extrusion auxiliary rings and thin sealing gaskets to finish one complete gearbox overhaul.

Q: What damage will fine dust particles mixed in gear lubricant bring?
A: Hard dust particles will gradually scratch sealing lip and trigger unexpected lubricant leakage long before it reaches expected service lifespan.

Q: Can I apply this seal kit on other gear assemblies for temporary emergency repair?
A: It is dimension‑calibrated specially for crane slew gearbox shaft. Improper cross‑fit will cause size mismatch and accelerate sealing performance failure.

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.
