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 core work does this seal complete during vehicle travelling?
A: It confines differential gear oil inside housing, and prevents muddy water, dust and grit from invading internal differential gears.
Q: Can this seal sustain high oil temperature under long‑haul heavy‑load driving?
A: FKM material tolerates elevated working temperature, it maintains good elasticity even under continuous heavy‑load operating status.
Q: Are these oil seal kits produced with strict dimensional specifications?
A: Every kit is precision machined to meet standard differential housing bore dimension for heavy‑duty truck assemblies.
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.
