This is how you measure a compression spring

How you measure a compression spring matters to the life cycle of the spring

There is a lot to consider when measuring a compression spring. We at EWES have documented the most important measures in a White Paper.

  1. Measure the diameter of the spring wire, marked ’d’ in the drawing.

  2. Measure the external diameter of the spring according to ’De’ in the drawing.

  3. Measure the unloaded length of the spring, indicated in the drawing as ’L0’.

  4. Count the number of turns on the spring wire. In the drawing example, there are 14 turns.

  5. If you know the loaded length, we can calculate the force of the spring. Loaded length is indicated ’L1’ in the drawing.

  6. Ready!
