Compression Springs from Coil Springs Direct

Compression springs are a common and affordable way to store energy as elastic strain and release it when necessary. Compression springs can be used in many settings due to their highly elastic and corrosion-resistant materials.

How Do Compression Springs Work?

Compression springs operate by twisting their wire around a spiral, causing a linear axial deflection. This twisting stresses the wire and is essential for its operation.


Manufacturers widely use compression springs as they are robust, easy to assemble and cost-effective. They come in many shapes and sizes, including cylindrical, conical, barrel, hourglass and helical compression springs. This allows them to meet many requirements related to force, fatigue, environment, size, and cost.

Many industries use compression springs in various applications, including:
