Canted Coil Springs

A canted also known as a slanted coil spring is an energiser spring that maintains a near-constant load throughout its deflection range. It benefits from a compact design that can expand to account for any wear or misalignment around the lip line of a seal, making them suitable for dynamic applications.

Common Sealing Applications

Canted coil springs are used in seal applications across various industries such as medical, aerospace and the oil industry. From ensuring reliable sealing in gaskets, O-rings, and components like shock absorbers to protecting wellheads and pumps from contamination and maintaining efficiency under harsh conditions, their high reliability and resistance to wear make them vital.

Non-sealing Applications

Canted coil springs, which can be aligned completely flat, are ideal for various non-sealing applications:

Latching: These springs provide consistent force to hold components in a fixed position until released, allowing for multiple removal and insertion cycles. They’re commonly used in latches and doors.
Connecting: Canted coil springs create secure yet removable connections, maintaining consistent force across a wide deflection range. This makes them suitable for applications with varying tolerances or thermal expansion.

Custom Canted Coil Springs

When designing custom-canted coil springs stainless steel is the most commonly used material for ensuring longevity and optimal performance. Several other factors should be considered, such as the required load capacity, range of motion, space constraints, and material choice.
