If you need a face seal that delivers reliable protection, extends equipment life, and supports optimal efficiency, FASeals is your trusted sealing partner.

Mechanical Face Seals

What Are Mechanical Face Seals?

Mechanical face seals—also called floating seals or duo cone seals—are built to perform reliably in harsh operating conditions, ensuring excellent sealing performance. They are generally classified into two designs: O-ring type and trapezoid type, which are distinguished by the shape of the secondary sealing element.

  • O-Ring Type Face Seals: This widely used floating seal design incorporates a Toric elastomer O-ring as the secondary sealing element.
  • Trapezoid Type Face Seals: In this version, the O-ring is replaced by a Toric elastomer ring with a trapezoid cross-section.
O-Ring-Type Mechanical Face Seal

At FASeals, every elastomer is engineered specifically for mechanical face seal applications. With a full range of NBR, HNBR, VMQ, and FPM materials available in different hardness levels, we deliver sealing solutions that perform in even the toughest environments.

To maximize equipment reliability, our seals are precisely matched to the machine interface and installed with proven methods and tooling. This ensures longer service life, reduced downtime, and dependable performance you can count on.

Heavy-Duty Applications of Mechanical Face Seals

In demanding machinery environments where conventional seals cannot withstand extreme loads or abrasive conditions, mechanical face seals provide the durability and protection required.

Tracked vehicles, construction equipment, conveyor drives, sand processing systems, cement mixers, mining machinery, and other heavy-duty applications place immense stress on sealing systems. In these harsh conditions, failures not only cause costly downtime but also lead to expensive repairs.

FASeals’ metallic mechanical face seals are purpose-built for such environments. Proven over years of field use, they deliver robust and reliable sealing performance that maximizes equipment uptime, extends service life, and ensures high productivity.

On tracked vehicles in particular, effective sealing is critical to protect bearings, rollers, and axle hubs from abrasive contaminants such as dust, sand, mud, stones, and soil. FASeals face seals provide this vital protection, keeping your equipment running smoothly and efficiently in the toughest working conditions.

About Mechanical Face Seals

For reliable performance, several key factors must be considered in the design and use of mechanical face seals:

  • Lubrication: Frictional heat at the contact surfaces between the static and dynamic components must be dissipated with proper lubrication. Continuous lubrication of the seal faces is essential to prevent pickup or galling.

  • Corrosion Protection: Measures must be taken to avoid corrosion during stationary periods.

  • Housing Requirements: Seal housings should be machined to recommended dimensions and surface finishes to ensure effective static sealing.

  • Assembly Practices: Cleanliness is critical during assembly, and proper procedures must be followed to maintain sealing integrity.
