Selecting and fitting
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. Check that the pilot bore can be bored to your shaft diameter with a keyway and set screw within the hub diameter. Contact AIMS if you need help with a bore or keyway.
Dimensions are as listed for each model and are for reference. Contact AIMS to confirm a measurement if it is critical to your application.
