Roller chain sprockets are toothed gears used with roller chain to transmit mechanical power.  As the sprocket rotates, the teeth of the sprocket interlock with the individual chain components and pull the chain.  Power is transferred from the driver end to the driven end of a system. Roller chain sprocket types include bushing bore, finished bore, machinable bore, and idler.
