Century Spring stocks a large selection of conically-tapered compression springs. 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. Probably 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.
