Douple Pitch chain

Category:

Double pitch roller chains

Apart from their pitch, double pitch roller chains are constructed on the same basis as single pitch chains in accordance with ISO 606 and meet the same standard specifications in terms of their dimensions. Unlike short pitch chains constructed to standard ISO 606, these chains are intended for use in conditions that place less demand on chain speed and power transmission. The principle difference is that the plates of double pitch roller chains are twice the length of the plates fitted to standard roller chains. Chains from the range constructed to the American Standard include versions with normal plate thickness or thicker plates, as well as variants with smaller or larger rollers.

Douple pitch specification Douple pitch highlights Product range and Application
  • The Elite douple pitch chains product ranger includeds soild pin chain as well as hollow pin versions
  • Both chians types are based on the respective standard chain versions, the only difference being that they are douple pitch.
  • ANSI standard: C2042, C2052, C2062, C2082…
  • BS/ Standard: 208B, 210B…224B
  • Wide range of products
  • Dimensions according to ISO 1275
  • Versions with small rollers and transport rollers available
  • All ELITE chain plates are manufactured using processes such as fine blanking and ball-drifting, so a particularly high contact ratio is guaranteed
  • Solid, case hardened rollers with good wear resistance
  • ELITE pins are smooth and have an extra hard surface for increased wear resistance
  • Douple pitch roller chain ISO 1275
