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: What practical functions will this seal realize in road construction scenarios?
A: It keeps hub bearing grease sealed inside housing, and blocks dust, muddy slurry and splashing water from getting into internal bearing parts.
Q: Can this oil seal hold good performance under long‑time vibration and temperature fluctuation during grading work?
A: HNBR rubber maintains stable elasticity under temperature changes, galvanized shell prevents rust even when exposed to humid working environment.
Q: Are these oil seal kits strictly produced according to standard mounting bore dimensions?
A: Each full kit is precision sized to satisfy standard drive axle hub bore tolerance for motor grader assemblies.
Q: Will frequent start‑stop rotation cause heavy wear to the sealing lip?
A: Optimized lip surface texture lowers frictional heat, effectively reducing lip abrasion under repeated start‑stop rotary cycles.
Q: What should we watch out for regarding the galvanized shell during installation?
A: Avoid hammering directly on local position; scratch on galvanized coating will lead to rust formation in later service period.
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.
