Getting to Know Spring Terminology

The process of ordering the right springs for your application begins with getting to know spring terminology.

Knowing what is meant by descriptive spring terms will allow you to compile a more precise set of specifics to use when ordering springs. An understanding of spring terminology will also help you to communicate spring failure problems to your spring manufacturer, assuring that the issues are addressed when ordering replacement springs.

Here are just a few common terms to get you started with your first lesson in spring terminology: 

  • Active Coils – Those coils which are free to deflect under load.
  • Buckling – Bowing or lateral deflection of compression springs when compressed.
  • Close WoundCoiled with adjacent coils touching.
  • Deflection – Movement of spring ends or arms under the application or removal of an external load.
  • Free Length – The length of a compression spring in the unloaded position.
  • Load – The force applied to a spring that causes a deflection.
  • Pitch – The distance from center to center of the wire in adjacent active coils.
  • Rate – Change in load per unit of deflection, generally given in pounds per inch.
