Tension Springs

Tension Springs

Tension springs are wound helical coils that are wrapped tightly together to create tension. Also called extension springs, tension springs provide extended force when the spring is pulled apart from its original length.

These springs typically have hooks, loops, or end coils at both ends of the body, which attach to other components. When these attached items move apart, the tension spring pulls them back together.

Tension springs oppose extension in the way they are wound. The actual tension of the spring varies depending on the load requirements of the application.
