Sprockets for Two Single-Strand ANSI Roller Chains
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.

Sprockets for Triple-Strand ANSI Roller Chain
Three rows of teeth make these sprockets compatible with triple-strand ANSI roller chain. The teeth are hardened steel, so they resist wear better and last longer than standard steel teeth. 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.

Taper-Lock Bushing-Bore Sprockets for Double-Strand ANSI Roller Chain
Switch out the bushing to install these sprockets on shafts with different diameters—no machining necessary. They have two rows of teeth for use with double-strand ANSI roller chain. Choose a taper-lock bushing that matches your shaft’s diameter. The bushing fits flush inside the sprocket hub for a thin profile.
Sprockets with hardened teeth have increased wear resistance for a long service life.
