Compression Spring
Compression Spring
A coil that pushes back. Loaded axially, returns to free length when released. The most common spring in industrial machinery.
Compression springs absorb axial loads and return to their free length when the load is removed. They sit at the heart of almost every mechanical device that needs to push, dampen, or store energy — automotive suspensions, industrial presses, valves, switches.
We stock standard compression springs in carbon and stainless across the most-requested sizes, and coil custom geometries from 0.1mm wire on small medical springs up to 10mm wire on heavy machinery.
