Tapered / Barrel Springs

Tapered springs, also known as conical springs, usually function as a type of compression spring that is tapered in shape. Due to their unique shape, they are considered more stable than similar springs like extension springs. Century Spring produces a variety of tapered springs, including barrel springs and constant rate tapered springs, spanning multiple sizes and finish options. One of the key applications where barrel springs are used is antenna springs.

Barrel springs and other tapered springs can be used in a wide variety of applications, including general industrial, aerospace, automotive, medical, and many more. We have more than 125 different tapered spring variations, available in an assortment of finishes.

CAD files for stock and standard tapered springs are available for download in our online store.

Tapered springs are characterized not only by their shape, but also by the fact that they are more laterally stable and less liable to buckle than regular compression springs. There is a necessary increase in the applied force to compress a tapered spring due to the flexibility of the larger-diameter coils causing progressive contact with one another. This characteristic can be a plus for spring-supported vibrating objects by reducing the resonant (bouncing) amplitudes commonly found in constant-diameter, spring-supported systems. However, its most beneficial characteristic is that it can be designed so that each active coil fits within the next, with the solid height equal to one or two thicknesses of wire.
