Extension Springs - Carbon & Stainless Steel Extension

All Century extension springs are wound with an initial tension force which offers a small deflection load for secure installation “holding”. The initial tension is equal to the minimum force required to separate adjacent coils. Each spring is of the constant diameter type with a variety of hook/loop styles. Spring Anchors are also available.

“Spring steel” is a term that includes music wire, hard-drawn wire and oil-tempered wire. Alloy steels for stock extension springs are offered only in 300 series stainless steel. Tolerances. Tolerances for extension spring rates depend upon the body-diameter to wire-diameter but are usually +/- 10% and +/- 5% on the diameter.

Custom Extension Spring Manufacturer

When selecting a hook for your extension spring, consider the allowable hook stress in torsion to be 30-45% depending on material of its minimal tensile strength, and for bending 75% of its minimal tensile strength.

ON THE RISK OF FATIGUE IN EXTENSION SPRING HOOKS

The simplest and cheapest way to design and manufacture an extension spring is to make the end hooks and spring body out of a single piece of wire and for the hooks to be the same diameter as the spring body. An example is shown in Figure 1.

Hooke's law - Wikipedia

An elastic body or material for which this equation can be assumed is said to be linear-elastic or Hookean. Hooke's law is only a first-order linear approximation to the real response of springs and other elastic bodies to applied forces. It must eventually fail once the forces exceed some limit, since no material can be compressed beyond a
