Mechanical Face Seals

Mechanical face seals are robust, highly wear-resistant sealing systems designed for equipment operating in extreme conditions where dirt, mud, sand, and water are present.

They protect critical driveline components from contamination and retain lubricant within the system, thus ensuring maximum uptime and reliability for heavy-duty machinery in construction, mining, and military applications.

Temperature Range

Reliable operation from -55°C to +200°C in extreme environments

High-Speed Capability

Rotational speeds of up to 10 m/s without compromise

Contaminant Protection

Seal design and proprietary abrasion-resistant materials safeguard against particulate ingress and corrosion

Eliminate Leakage

Precision contact surfaces eliminate fluid loss in critical systems

Design & Performance Features

Mechanical face seals are engineered for durability in the harshest environments. Key features include:

Close-grained cast iron rings for superior wear and corrosion resistance
Operates at rotary speeds up to 10 m/s
Exceptional tribological performance to prevent seizure and scoring under extreme conditions
Dynamic sealing interface positioned at the outer edge of the seal ring
Elastomer options: NBR, HNBR, VMQ, and FPM for different thermal and chemical resistance requirements
Self-centering design compensates for shaft misalignment and eccentricity
Adaptor solutions simplify machining and reduce complexity
Lubrication is essential to cool and lubricate the seal

Engineered for your application

Every mechanical face seal is engineered in collaboration with your team. Each design is specified to meet your application requirements and provide optimal performance and seamless integration with your equipment.

Design configurations include:

Toroidal (O-ring type) for heavy-duty applications
Trapezoidal (square bore type) for simplified housing designs
Adaptors for easy installation without the need to machine complex ramp profiles
Asymmetric options for specialised projects
Material combinations tailored for extreme abrasion and temperature conditions

Why FTL?

FTL has decades of engineering expertise from specification through to integration. From housing tolerance and surface-finish guidance to assembly best practices, our aim is to support end-to-end implementation of our solutions.
We offer a broad range of solutions, tailored to your particular application. We work in consultation with you to understand and match your requirements.

Our solutions are designed to minimise complexity and cost, and accelerate integration into your systems. Where required, we design solutions to retrofit into existing housing envelopes. Our solutions are built to deliver outstanding value for uncompromising performance.

In-house validation in our test centre ensures high reliability in harsh conditions with long service life and minimal maintenance.

Applications

Mechanical Face Seals ensure long-term reliability for track rollers, final drives, hub seals, suspension arms, tension sprockets, brakes, and gearboxes in construction, mining, and military vehicles.
