compression-springCompressions Springs

Compression springs are helical springs with an open-coil configuration designed to store energy or to resist a force applied along the axis of the coil. The most common form of compression spring is a straight cylindrical coil spring with the ends squared (closed), and a common example is a ball point pen spring. The end coils may also be ground to improve squareness and reduce buckling. Squared and ground compression springs are normally supplied with a bearing surface of at least 270 degrees.

Cone Compressions Srings

Cone Compression springs are often specified where the large end is meant to work in a bore and the small end is meant to work over a rod. They offer the advantage of a reduced solid height compared to straight compression springs, especially when capable of "telescoping."

Cone Springs are designed to provide a near constant spring rate and a solid height lower than a normal spring. Each spring features a variable pitch to achieve the constant spring rate and coils which nest during deflection to provide a solid height approximately equal to two wire diameters.

torsion springsTorsion Springs

Torsion springs are helical springs that exert a torque or rotary force. The ends of torsion springs are attached to other components, and when those components rotate around the center of the spring, the spring tries to push them back to their original position. Although the name implies otherwise, torsion springs are subjected to bending stress rather than torsional stress. They can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the body centerline axis.

Extension Springs

Extension springs, also known as a tension spring, are helically wound coils, wrapped tightly together to create tension. Extension springs usually have hooks, loops, or end coils that are pulled out and formed from each end of the body. The function of an extension spring is to provide extended force when the spring is pulled apart from its original length.

This type of spring is normally close wound but can have pitch to reduce friction between the coils. They offer resistance to twist or rotationally applied force. Depending on the application, torsion springs can be designed to work in a clockwise or counter-clockwise rotation, thus determining the direction of the wind.
