COMPRESSION SPRINGS are open-coil helical springs wound or constructed to oppose compression along the axis of wind. Helical Compression Springs are the most common metal spring configuration. Generally, these coil springs are either placed over a rod or fitted inside a hole. When you put a load on a compression coil spring, making it shorter, it pushes back against the load and tries to get back to its original length. Compression springs offer resistance to linear compressing forces (push), and are in fact one of the most efficient energy storage devices available.

Configurations: The most common compression spring, the straight metal coil spring, has the same diameter for the entire length. Other configuration options for compression coil springs include hourglass (concave), conical springs and barrel (convex) types. The straight coil spring configuration is the standard coil type for Stock Compression Springs.

Applications: Compression Metal Springs are found in a wide variety of applications ranging from automotive engines and large stamping presses to major appliances and lawn mowers to medical devices, cell phones, electronics and sensitive instrumentation devices. Cone shape metal springs are generally used in applications requiring low solid height and increased resistance to surging.

Dimensions: Outer Diameter, Inner Diameter, Wire Diameter, Free Length, and Solid Height.
Free Length is the overall length of a spring in the unloaded position.
Solid Height is the length of a compression spring under sufficient load to bring all coils into contact with adjacent coils.
Spring Rate is the change in load per unit deflection in Newtons per millimeter (N/mm).
