What are Canted Coil Spring Seals?

Canted coil spring seals, helical torsions, or spiral springs are mechanical devices that provide adequate sealing for dynamic applications. They are cylindrical bodies made from elastomeric materials such as rubber or thermoplastic compounds. A helical torsion spring is inside the body made from stainless steel or other corrosion-resistant alloys.

The unique design of canted coil springs allows them to combine axial and radial deflections during operation. This enables them to accommodate misalignment, eccentricity, and other forms of shaft movement while maintaining an effective seal.

Advantages of Canted Coil Spring Seals

Canted coil springs offer several advantages over traditional sealing methods. Let’s take a look at some key benefits:

1. Superior Performance

One significant advantage of canted coil springs is their superior performance compared to other seals. Combining elastomeric materials with metal springs allows these seals to withstand high pressures, temperature extremes, aggressive media, and harsh operating conditions without compromising their sealing capabilities.

2. Self-Compensating Design

The self-compensating design is another notable advantage offered by canted coil springs. The helical torsion springs inside these seals automatically adjust their position according to shaft movement or misalignment during operation. This ensures consistent sealing performance even under dynamic conditions.
