Canted Coil Springs​

Canted coil springs provide a consistent load during deflection. Their compact design allows them to flex around seal lips, adapting to wear and misalignment, which makes them effective in dynamic settings. Stainless steel is often used for these springs due to its strength, resilience, and resistance to corrosion, though other materials may be suggested based on specific application needs.

Sealing Applications

Our canted coil springs are integral to sealing systems where consistent force is essential. These springs are widely employed in sectors such as:

  • Defence: Used in mission-critical equipment seals, ensuring performance in demanding and often hostile conditions.
  • Robotics: Ensuring smooth articulation and reliable sealing in robotic joints and moving assemblies, particularly where repeat motion is frequent.
  • Green Energy: Found in seals for turbine systems and hydrogen fuel components, where long-term durability and resistance to environmental extremes are essential.

Their excellent fatigue resistance and adaptability make them ideal for precision sealing in both static and moving applications.

Non-sealing Functions

Canted coil springs can be manufactured to lay flat, making them particularly useful in roles beyond sealing. Some typical applications include:

  • Retention Systems: Offering a controlled holding force in modular component assemblies, ideal for quick-release mechanisms or easily replaceable parts.
  • Precision Connectors: Ensuring uniform contact pressure in high-performance electrical connectors, often used in test equipment and high-speed data transfer.
  • Thermal Compensation Assemblies: Their flexibility allows them to maintain effective pressure even as materials expand or contract with temperature fluctuations.
