Compression springs are a type of wire spring engineered to resist compressive forces or store energy when pushed. Commonly used in everything from industrial equipment and motors to household appliances and medical devices, these springs compress under a load applied to their ends and return to their original shape when the force is released. This push-back action makes them essential in thousands of mechanical applications requiring durability, reliability, and consistent performance.
Typically manufactured as cylindrical helical coils made from round wire, compression springs can also be customized into conical, barrel-shaped, oval, or hourglass forms to suit specific design needs. The wire itself may be round, square, or rectangular, depending on the application. As one of the most widely used spring types, compression springs are found across a wide range of industries, including automotive, aerospace, electrical switchgear, military and defense, medical devices, consumer electronics, power generation, industrial machinery, firearms (such as custom gun and firing pin springs), and more.
Compression springs are essential components across a wide range of industries that demand durability, precision, and performance under load.

Compression Springs are open-coil helical springs that offers resistance to a compressive force applied axially. Helical compression springs are used to resist applied compression forces or to store energy in a push mode. Compression springs have the most common configuration and are most commonly used in automotive, aerospace and consumer applications. Most compression springs are a straight cylindrical spring made of round wire. Ace Wire Spring & Form, a manufacturer of compression springs produces a variety of compression types, shapes, and specific specifications. Click here for compression springs specifications.
Compression springs from a manufacturer come in a variety of types including: Conical Compression, Barrel, Hourglass and Cylindrical shapes and may have various spacing or no spacing at all between coils.
Wire Selection: rectangular, round, square or special-section. Round being the most adaptable.
Compression Spring Mandatory Specification: the functional design characteristics.
Compression Spring Secondary Specification: the secondary characteristics, which is useful for reference and should be considered advisory data.
Dimensional Limits: governed by the space allotted with regard to allowable solid height and outside and inside diameters.
Spring Stress Level: determined by the dimensional limits together with the load and deflection requirements. Our compression springs are stress-relieved to remove residual bending stresses produced by the coiling operation.
For Compression Springs – Rate which is the change in load per unit deflection, may be determined by the following procedure:
The solid height of compression springs is defined as the length of the spring when under sufficient load to bring all coils into contact with the adjacent coils and additional load causes not further deflection. Solid height should be specified by the user as a maximum, with the actual number of coils in the spring to be determined by the spring manufacturer. As square or rectangular wire is coiled, the wire cross-section deforms slightly into a keystone or trapezoidal shape, which increased the solid height considerably. The dimensional change is a function of the spring index and the thickness of the material.
