Our Part Numbers Have Changed

Since we have created the new website, we have updated our dimensional part numbers to not have any decimal points. However, we have kept the three decimal spaces so remember to add the extra zeros where needed.

Previous Part Number

PE049-375-26.235-SST-1.750-MH-N-IN

New Part Number

PE049-375-26235-SST-1750-MH-N-IN

 

The Spring Store By Acxess Spring Part Number System In Inches 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 inches.

  • 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 indicates Outer Diameter = OD
  • The third series indicates Total Coils = TC
  • The fourth series indicates Material Type
  • The fifth series indicates Length Inside Hooks = LIH
  • The sixth series indicates Hook Type
  • The seventh series indicates Finish
  • The eighth series indicates Unit of Measure Inches = IN

 

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

Extension Spring Part Number Example In Inches:

PE049-375-26235-SST-1750-MH-N-IN

 

  • P = Part Number
  • E = Extension Spring
  • 049 = 0.049 Wire Diameter = WD
  • 375 = 0.375 Outer Diameter = OD
  • 26.235 = Total Coils = TC
  • SST = Material Type
  • 1.750 = Length Inside Hook = LIH
  • MH = Hook Type
  • N = Finish
  • IN = Unit Of Measure Inches

Nomenclature:

 

Material Type: BC = Beryllium Copper, HD = Hard Drawn, MW = Music Wire, OT = Oil Tempered, PB = Phosphor Bronze, SPR = Spring Steel, SST = Stainless Steel

Hook Type: CO = Closed Over Hook, MH = Machine Hook

Hook Type: * = Double Loop, ** = Side Hook/Loop, *** = Extended Hooks

Finish: BO = Black Oxide, GI = Gold Irridite, N = None, Z = Zinc

Unit of Measurement: IN = inches, MM = millimeters
