5. 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: How is its tolerance to engine oil and gear oil?
A: NBR material delivers reliable oil resistance under conventional equipment working conditions.

Q: Is this seal suitable for working environments with floating dust?
A: The integrated structure can prevent outside dust and impurities entering internal components.

Q: Are all products manufactured following unified dimensional standards?
A: Every oil seal is precisely produced to match standard shaft and housing installation sizes.

Q: Will the sealing lip lose elasticity rapidly after long continuous operation?
A: Anti-aging ingredients are added to slow down hardening and extend service life.

Q: Will all the sealing pieces inside the kit be sufficient for full engine overhaul?
A: Every required sealing part for complete engine disassembly is included. You do not need to purchase extra separate seals during maintenance.

Q: What common engine failures can this oil seal kit effectively prevent?
A: It avoids crankshaft and camshaft oil leakage, and stops oil seepage on joint surfaces caused by long-time engine vibration.

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.
