ANSI Standards for Your Grade 100 Chain

Did you know that the dimensions, interoperability and sprocket fit of our roller chains are all built to standards that ensure a perfect fit every time? These rigorous requirements define:

  • Pitch
  • Roller width
  • Roller diameter
  • Plate height
  • Plate thickness
  • Pin diameter
  • Overall width
  • Average tensile strength
  • Average weight per foot


Each of these measures helps you determine which grade 100 chain is right for your unique application. For instance, the average tensile strength of the mid-range 100 chain is 25,353 pounds — plenty heavy enough for many common applications.
