Selection
Springs are organized in order of increasing diameter and wire size.

Note that in each category the spring rate decreases as the free length increases.

After selecting the proper outside diameter of the spring needed, choose a range for wire diameter and then select a range for free length. The broader the range entered the more options will be shown.

Units of Measure
All units are in Inches, Pounds for Loads and Pounds per Inch for spring rate.
To convert to metric units multiply using the following factors.
  • Inches to millimeter = 25.4
  • Pounds to Newtons = 4.45
  • Lbs/Inch to N/mm = 0.175
