Compression Spring Calculator

  • One Load, Two Load, Rate Based & Dimension Compression Spring Calculations

The Springulator® features four different types of compression spring calculators, which check spring stress and provide spring design information.

Compression Spring Calculations & Stress Check

The Springulator is able to generate a variety of data to assist with the design of your compression spring. Depending on your spring type, enter the load or rate information plus the total coils (Nt), the free length (L), the wire diameter (d) and the mean diameter (D) to calculate data including your compression springs:

  • Index
  • Part Weight
  • Tensile Strength
  • and more

By selecting your material type, the Springulator compression spring calculator is also able to check your design to see if it falls within allowable stress limitations. Click the button and a stress chart will be generated that shows the acceptable stress limitations, and pinpoints the stress at different load heights, as applicable to the type of compression spring you are calculating.

The Springulator compression spring calculator is designed for engineers and designers. It has been built with a number of checks that will not allow you to calculate a spring if the data you have entered will not result in a feasible design. If you aren't sure the Springulator is operating correctly, please enter the data and check the results on the sample values and results page.

Compression Spring Direction of Wind

If your compression spring "screws" into another mating part, it is important to consider the direction of the spring's wind. Compression springs can be left wound or right wound. To determine a compression spring's direction of wind simply hold the spring in your hand with your fingers placed around the outside of the body and your thumb pointing straight up. If the last coil ends in the same direction that your fingers are pointing, that is the hand (direction of wind) of the spring. Read more on wind direction of a compression spring.

Compression Spring End Types

Compression spring calculations are affected by the type of spring end. Compression spring ends affect the performance of your spring, so be sure to consult with your Newcomb Spring representative to determine the best end type for your application. Learn more about compression spring ends types in our compression spring design resources section.
