Overview

• Double pitch straight sideplate chains are based on the single pitch chains constructed according to ISO 606; except for the pitch, they meet the same standard specifications with respect to their dimensions with the added benefit of straight edge sideplates for conveying purposes and for added fatigue strength. these chains are intended for use in conditions in which demands on speed and power transmission are lower.
• The principle difference being that the plates of double pitch roller chains – as the name implies – are twice the length of the plates fitted to standard roller chains.
• In addition to the above, 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.
• Double pitch hollow pin roller chains are normally only available in a version with straight plates as a bush or roller chain.
• One of the main advantages here is that the longer pitch allows transport rollers to be fitted, which in many applications significantly reduces friction and tensile forces within the chain.
