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.

Get the same sizing versatility as quick-disconnect sprockets while using less space. The bushings for these sprockets mount flush inside the sprocket hub for a slim profile. The same sprocket can be used with different shaft diameters; choose a compatible taper-lock bushing with the bore size you need.

Since these sprockets grip bushings more tightly than taper-lock sprockets, they’re often used in high-torque applications. The same sprocket can be used with different shaft diameters; choose a compatible split-tapered bushing with the bore size you need.
Sprockets for P1- and Q1-Style bushings have a keyway that fits a matching key on the bushing.

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.
