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 does this sealing assembly display?
A: The rubber lip section is dark brown, and the outer steel shell shows matte silver‑grey metallic surface.

Q: Where will this oil seal kit be fitted on wheel loader?
A: It installs at final drive shaft housing opening, surrounding the rotating drive shaft for rotary dynamic sealing protection.

Q: What core working performance does this seal deliver under construction site conditions?
A: It holds gear lubricant inside final drive housing, and isolates outside mud, gravel and splash water away from internal planetary gear parts.

Q: Can this seal keep stable elasticity under continuous heavy‑load operation and rising oil temperature?
A: FKM material performs well under high‑temperature oil environment, it can adapt to periodic mechanical vibration without seal shifting.

Q: Will long‑term rotating friction bring obvious abrasion to sealing lip?
A: Optimized lip geometry reduces friction heat, slowing lip wear under persistent rotary movement of axle shaft.

Q: Shall we add extra sealant when fitting this oil seal kit?
A: Light‑coated sealant is suggested on shell outer surface for aged mounting housing; it is not compulsory for brand‑new bore.

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.
