Common Uses for Compression Springs

Compression springs, integral to modern mechanical assemblies, offer a compelling study in efficiency and functionality. These helical springs, designed to bear compressive forces, find compression springs uses across a broad spectrum of industries, including automobiles, medical devices, and electronic switches.

How do Compression Springs Work?

Compression springs are designed as open-coil helical springs that counteract compressive forces. This means when a force or heavy object is applied, the spring compresses, storing this energy temporarily. Once the force is removed, the spring then releases this stored energy, returning to its original shape.

How Long Do Compression Spring Last?

The lifespan of a compression spring depends on various factors including the material, design, workload, environmental conditions, and how frequently it is cycled. Typically, a well-designed compression spring made from quality material can last from thousands to millions of cycles. In less demanding applications, springs can last several years without noticeable degradation. However, their lifespan may be significantly shorter in high-stress applications or harsh environments. Proper maintenance and usage within specified limits are key to maximizing a compression spring’s longevity.
