Choosing the right option

Choose the sprocket by chain size and number of teeth. The chain size must match your chain, and the tooth count sets the speed ratio. Then choose a taper lock bush of the series shown for that model, bored to your shaft diameter with a keyway. Check that the bush series covers your shaft diameter.
