ANSI Heavy-Duty Roller Chain

Heavy-Duty roller chains are also commonly referred to as heavy roller chain or heavy-duty roller chain. Something important to note about these chains is that they utilize thicker side-plates than standard chains, this means that single-strand (simplex) heavy roller chain will run on the same sprockets as standard (excluding double-single type) but double strand (duplex) heavy roller chains require specially manufactured sprockets due to the need of increased width between the sets of teeth.
