Compression Springs

Helical Springs

Compression Springs also referred to as helical springs, or coil compression springs, come in a variety of different body shapes such as conical or concave springs (barrel springs), convex springs (hourglass), or tapered springs (one end has a larger diameter than the opposite end).

The related characteristics of each coil compression spring exhibit open coils in a helical configuration and exert resistance to compressive forces when applied axially. Most coil compression springs are made from round wire, but can be made from square, rectangular or a host of other uncommonly shaped wire specific to various applications and needs.

Tips for Designing a Compression Spring

Although compression springs appear to be simplistic in design, big or small compression springs are very complex. There are a number of design considerations that need to be given prior to specifying a compression spring to fit in any given application. First, a designer needs to look at the space allotted for the spring which will help to determine the dimensional limits and if those limits will allow the part to meet the load requirements for the application. As these limits are specified, it is then necessary to determine the stress levels at which the spring will function. If the design shows that the spring is overstressed, the spring will not function properly and possibly lead to costly design changes.

Rowley Spring and Stamping offers design assistance. We are happy to have our staff lend their expertise to help determine the right spring for an application.

Compression springs can be found in many different applications from simple ball point pens to precision surgical equipment and the world’s most sophisticated aircraft.
