Double sprockets (aka duplex sprockets) are designed with two sets of teeth so each can engage with a different chain in applications with two chains running parallel, commonly used for even load distribution or to drive two separate mechanisms simultaneously. WM Berg manufactures double sprockets in 303 stainless steel and anodized aluminum, in hubless, clamp hub and pin hub styles. Our double chain sprockets are designed to operate with our Min-E-Pitch cable chain. Note that double sprockets with a pitch diameter of .750 and smaller are recommended for idler use only.
We also manufacture custom double sprockets.
