What is a Compression Spring?

To the untrained eye, a compression spring would not be distinguishable from any other type of spring. While similar in general appearance, spring types are actually engineered quite differently, depending upon the job they need to do.

Compression springs are designed to keep components from coming together. The coil of a compression spring is open, and not as tightly wound as other types of springs. They are often manufactured from a larger gauge of wire for strength in resisting compressive forces. Compression springs are at rest when they are extended.

The most widely used type of spring, compression springs come in a variety of sizes and shapes, with cylindrical being the most common. Compression springs can be made from a variety of materials, depending on the temperature, stress, and corrosion resistance requirements associated with the application.

Used in many different types of machinery and products, compression springs are commonly found in electronic devices, watches, mattresses, switches, compressors, door locks, and writing pens. Compression springs work to resist force and store energy in a wide array of applications.

Varying sizes of compression springs are used in a diverse range of manufacturing industries including automotive, medical, tools, appliances, and more.
Compression springs are usually coiled at a constant diameter, however they can be made to be conical, concave (barrel), convex (hourglass), or other configurations, depending on specific application requirements.
