Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Taper-lock bushings mount flush inside the sprocket hub for a slim profile. Mount a bushing (sold separately) on your shaft, slide the sprocket over it, and tighten the included set screws. As you tighten, the bushing grips the shaft and pulls it into your sprocket for a secure hold.

Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.
