- Extension Spring
Quote Form
-
Extension springs which absorb and store energy by offering resistance to
a pulling force. Various types of ends are used to attach the extension
spring to the source of the force.
- Compression Spring
-
A compression spring is an open-coil helical spring that offers
resistance to a compressive force applied axially. Compression springs are
usually coiled as a constant-diameter cylinder. Other common forms of
compression springs--such as conical, concave (barrel), convex (hourglass),
or various combinations of these--are used as required by the application.
While square, rectangular, or special-section wire may have to be specified,
round wire is predominant in compression springs because it is readily
available and adaptable to standard coiler tooling.

- Torsion Spring
- Torsion springs, whose ends are rotated in angular deflection, offer
resistance to externally applied torque. The wire itself is subjected to
bending stresses rather than torsional stresses, as might be expected from
the name. Springs of this type are usually close wound, reduce in coil
diameter, and increase in body length as they are deflected. The designer
must consider the effects of friction and arm deflection on the torque.
Special types of torsion springs include double torsion springs and
springs having a space between the coils to minimize friction. Double
torsion springs consist of one right-hand and one left-hand coil section
connected together, and working in parallel. The sections are designed
separately with the total torque exerted being the sum of the two.

Stampings
- A Stamping is a "formed" piece of material, usually Sheet metal,
that has some or all of the following characteristics: Holes, Bends,
Radius, Dimples, Folds and any thing else an engineer can think
up.
