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 appearance does this sealing assembly present?
A: The rubber sealing part is matte black, and the steel shell shows natural metallic silver‑grey finish without extra paint coating.

Q: Where is this oil seal kit installed on motor grader?
A: It is pressed into engine crankshaft housing bore and surrounds rotating crankshaft to complete dynamic rotary sealing for motor grader engine assembly.

Q: What practical performance does this seal deliver on road‑building job sites?
A: It keeps engine lubricating oil sealed inside crankcase chamber, and blocks construction‑site dust, fine sand and muddy splashes from invading internal engine moving components.

Q: Can this seal sustain stable sealing under long‑time engine vibration and working temperature fluctuation?
A: NBR rubber maintains reliable resilience under continuous mechanical vibration, solid stamped steel shell avoids shell deformation under frequent temperature changes.

Q: What damage should we avoid for electrophoretic shell during handling?
A: Prevent sharp objects scratching coating surface; once protective layer peels off, bare steel will rust gradually and cause seal displacement.

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.
