Roller chain is a type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery including conveyors, wire-and-tube-drawing machines, printing presses, cars, motor cycles, and bicycles. It consists of a series of short cyclindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
