Extra Capacity Chains Heavy Series Roller Chains Heavy Series roller chains are built for heavy duty power transmission applications which require additional shock load capacity or link plate strength. They are dimensionally equivalent to the ASME/ANSI standard chains, except that the link plates are one size thicker. Single strand chains operate over standard ASME/ANSI sprockets (hardened teeth recommended), however multiple strand chains require special sprockets due to their increased transverse pitch.
