Reduce assembly time when setting up a system to drive two different roller chains from a single sprocket. Also known as double single sprockets, these sprockets have a row of teeth on each side, which is helpful for keeping consistent spacing between your chains. They’re often used to daisy chain powered conveyors together. For a custom fit on your shaft, machine these sprockets to your exact specifications. They come machined to the shaft diameter listed and are machinable up to the maximum shaft diameter size.
