The Spring Store By Acxess Spring Part Number System In Metric Millimeter For Extension Springs

We have developed an easy stock spring part number system using the actual dimensions of the spring. This part number system for springs was developed to facilitate the creation and understanding of part numbers for springs. By using the actual dimensions of the spring in the spring part number we have made our part numbers for springs simple, but yet descriptive of the actual spring measurements in real time. Our part numbers consist of a series of numbers to describe each individual spring. Each part number is separated by hyphens to indicate different dimensional characteristics of a spring. Each series describes a different dimension. Below you will find a breakdown explanation of how The Spring Store part number system works for extension springs in metric millimeter.

  • The letter P stands for Part Number
  • The letter E stands for Extension Spring
  • The first series of numbers indicates Wire Diameter=WD
  • The second series, following the first hyphen, indicates Outer Diameter=OD
  • The third series, following the second hyphen, indicates Total Coils=TC
  • The fourth series, following the third hyphen, indicates Material Type
  • The fifth series, following the fourth hyphen, indicates Length Inside Hooks=LIH
  • The sixth series, following the fifth hyphen, indicates Hook Type
  • The seventh series, following the sixth hyphen, indicates Finish
  • The eighth series, following the last hyphen, indicates Unit of Measure Metric Millimeter=MM

Please look at the part number example below for a further explanation.
