Extension Spring Advantages

Extension springs are helically wound coils wrapped tightly together. This design produces high initial tension, which offers resistance when extended. As pulling forces are applied, these springs try to return to their original positions.

Also called tension springs, they have many beneficial performance characteristics.

  • Create Loads When Stretched
  • Very Little Gap Between Coils
  • Have High Tensile Strength
  • Highly Durable

These springs often feature end coils, hoops, eyes, loops, or other interface geometry on their ends. Each end is attached to components, and their natural resistance tries to bring them back together as pulling forces are applied.

Extension springs can be tailored to suit application requirements. Initial tension relates to how tightly together the spring is coiled, and this tension can be manipulated to accommodate specific load requirements.

A Versatile Spring Type

Extension springs are frequently used to provide a return force to components that extend in an actuated position. Examples include:

  • Trampolines
  • Screen Doors
  • Exercise Equipment
  • Appliances
  • Toys
  • Agricultural Machinery
  • Weapons
  • Carburetors
  • Vise-Grip Pliers
  • Garage Door Assemblies
