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: Which key mechanical position is this oil seal kit designed for installation?
A: It is assembled on swing‑drive rotating shaft assemblies of excavator digging construction machinery.

Q: Does this complete overhaul kit include matched backup rings and small auxiliary gaskets?
A: Yes, supporting backup rings and assorted small gaskets are included for full swing‑drive system maintenance work.

Q: How will this sealing kit behave when contacting hydraulic gear oil and multi‑purpose chassis grease?
A: HNBR rubber delivers outstanding oil‑aging resistance and maintains low swelling rate facing mineral‑based lubricants.

Q: Can on‑site mining maintenance workers reuse these seal components after dismounting from shaft assembly?
A: Re‑installation is not recommended. Lip radial pre‑compression force will drop after removal and bring hidden leakage risk.

Q: What precautions should we take for long‑term storage of these spare seal kits?
A: Store in dry shady warehouse, avoid sharp collision, heavy stacking pressure and continuous ultraviolet rays.

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.
