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 do these sealing components present?
A: Rubber parts are matte jet‑black, and metal shells show silver‑grey after zinc‑coated anti‑corrosion treatment.

Q: Does this complete overhaul kit contain matched backup rings and small auxiliary gaskets?
A: Yes, complete supporting backup rings and assorted small gaskets are included for full gearbox system maintenance service.

Q: How will this sealing kit perform when contacting heavy‑duty gear oil and multi‑purpose chassis grease?
A: FKM fluorine‑rubber delivers excellent heat‑resistant and oil‑resistant performance and maintains low‑swelling feature for mineral‑based lubricants.

Q: What points should we pay attention to for long‑term storage of spare seal kits?
A: Keep in cool dry ventilated warehouse, avoid heavy stacking deformation, surface scratch and long‑time ultraviolet radiation exposure.

Q: Can on‑site crane service technicians reuse these seal components after removing from shaft assembly?
A: Re‑installation is not advised. Lip radial pre‑compression force will decrease after disassembly and bring hidden lubricant leakage risk.

Q: Does this overhaul repair kit contain matched backup rings and small auxiliary gaskets?
A: Yes, complete supporting backup rings and assorted small gaskets are included for full axle‑system maintenance service.

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.
