Product Description
What are compression springs?
Compression springs are open-coil helical springs designed to resist axial compressive force. They store mechanical energy as their coils move closer together and return that energy when the load is released.
Working Principle
How this spring type works.
An axial load shortens the spring and twists the wire along the helix. The resulting torsional stress creates a restoring force. Spring rate is controlled by wire diameter, mean coil diameter, active coil count, material, and end configuration.
