Extension Springs

An extension spring or tension spring is a length of tightly coiled metal, usually steel with hooks or loops at either end. Extension springs absorb and store energy.

What does it do?

An extension spring is a component that creates a resistance to a pulling force. Extension springs work by trying to pull two objects back together. The attached spring is pulled in opposite directions and the force and the stored energy to pull the two objects back together.

  • Material – Steel or stainless steel
