Oil seal14Y-18-00016

Core Features

Dynamic sealing and leak prevention: The double-conical floating seal ring rotates in close contact with the surface, and the O-ring pre-tightens to compensate for the gap, preventing gear oil leakage and the intrusion of external impurities.

Self-cleaning seal: The conical structure can scrape off attached mud and sand, reducing wear on the sealing surface.

Lubrication self-compensation: An oil film forms between the sealing surfaces, reducing friction and wear and extending service life.

Impact adaptation: The floating seal ring can float slightly, absorbing vibrations and impacts from the traveling system and preventing sealing surface misalignment failure.

Product Superiority

Original factory precision fit: The float seal ring size and cone angle perfectly match the wheel hub/gearbox tolerances, allowing for direct replacement without adjustment.

Reliable materials: The float seal ring is made of chromium-molybdenum alloy cast iron (HRC 65–72), wear-resistant and impact-resistant; the O-ring is made of nitrile rubber (NBR), resistant to mineral oil and aging.

Stable sealing: The double cone surfaces fit tightly, ensuring long-lasting O-ring preload and a dynamic seal life of ≥4500 hours.

Self-compensating design: Automatically compensates for installation and wear clearances, reducing maintenance frequency.

Strong resistance to contamination: Suitable for high-dust and muddy conditions, preventing impurities from entering and damaging the seal and transmission components.

Installation and Maintenance Points

Before installation, clean the sealing cavity and floating seal ring to remove burrs, oil, and impurities to avoid scratching the sealing surface.

During installation, ensure the conical surfaces of the floating seal rings are aligned, and the O-ring is inserted into the groove, pressing it in evenly to avoid twisting.

Tighten the housing bolts to the specified torque to ensure uniform pressure on the floating seal rings.

Check for leaks every 2000 hours and replace the floating seal ring every 4500 hours to prevent wear/aging failure.

Fit scenarios and value

Suitable for: Rotating dynamic seals such as wheel hubs and final drive gearboxes; suitable for heavy-duty, high-pollution operating environments.

Core benefits: Prevents gear oil leakage, protects drive components, extends system life, and reduces downtime maintenance costs.
