Compression Springs

In stock

Compression springs, also known as coil springs, are designed to store energy when compressed and then release it when expanded. Their key qualities are their spring rate, which quantifies the force necessary to compress the spring a certain distance, and their solid height, the lowest height to which the spring can be crushed.

Key Factors to consider when choosing a spring for an application include Spring Material and the Working Environment, Spring Dimensions in both compressed and non-compressed states, Max. Load and Deflection.

It is available in both Music Wire material, which is ideal for temperatures between -30 C and +120 C and for use in dry environments, and stainless Steel material, which is ideal for temperatures between -200 C and +250 C and for use in both dry and humid or wet environments. Widely used across various industries to provide effects such as suspension, shock absorbtion and enabling push-to-open functionality. Material: Stainless Steel, Carbon Steel Series Code:
