Compression Springs

A compression spring is an elastic coil, made of spring steel - its spring characteristic is that it absorbs force or provides resistance. A compression spring can be used as a pure energy accumulator, shock absorber, vibration damper or force generator.    The commonest type of metal spring, they are very effective at building up energy, and therefore have countless potential applications. The compression spring has gaps between its coils in an unloaded state. The distance b...

Tension Springs

Tension springs are tightly wound coils that are designed to operate with tension. The spring stretches to a specific length as the load/force is applied to it.  In an unloaded position, the loops of the spring are touching, with either a loop or hook attached at one end, and it is when this attachment is directed with force that the spring stretches. When these components are pulled apart, usually from either side, the spring tries to hold itself together, causing the springing action, unt...

Torsion Springs

Torsion springs are designed to maintain a rotational pressure between two surfaces. The shape of a torsion spring is a small, coiled section of wire with two sheered and protruding ends. Generally, torsion springs should be designed to wind the same direction as the coil, which can be clockwise or counter clockwise. Otherwise, their maximum load is considerably lower. Torsion springs are made in a variety of metals or even plastic, although they typically provide less force than their metal cou...

Wire Form Springs

Wire forms are finished shaped wire that have been manufactured from wire spools into a specified configuration. They can take nearly any form, often featuring springs with custom ends. Essentially a wire form is a length of wire that has had an exterior force applied to it in order create a specific shape designed for a specific job. The wire form can be bent, cut, cut with angles, wound right/left, shaped with closed coils, can have additional pieces added to it, and just about anything that a...

A History of Springs

Bows and Arrows. If you include non-coiled springs, springs have been around forever. A great example of a non-coiled spring is a bow and arrow which as we know, were used to help with food and protection from 64,000 years ago - one of the earliest spring technologies.  Egyptian Chariots. 3,600 year-old chariots depict pharaohs and warriors proudly riding into battle on horse-drawn chariots including spoked wheels, springs, shock absorbers, anti-roll bars, and a convex-shaped rear...
