Compression applications are the most common use for volute springs, which are comprised of flat metal strips that are wound together to form helical spirals. The type of material, the diameter, the stroke, the intended application, and the type of end attachment are all important specifications. Volute springs are typically put to use in applications that call for a compression spring to have a particularly long fatigue life or a particularly high level of spring force repeatability. They are available in a range of sizes to accommodate the different materials, applications, and required levels of force. While others have two ends, single-ended volute springs are the most common type. The compression spring that can be found in the spring manufacturer is an example of an application of the volute spring that is very easy to recognize.

Garter springs are spring coils whose ends are joined to form circular springs. Garter …
