STANDARD ROLLER CHAINS
Standard Roller Chains or bush roller chain are chain drives. They are most commonly used for transmission. They are used in various mechanical power machines such as domestic, industrial & agricultural machinery. They are sometime used in conveyors, wire- and tube-drawing machines, large printing presses, cars, motorcycles, bicycles & many more. Standard roller chains are basically made up of a series of short cylindrical rollers that are held together by side links. Now these rollers are driven by a toothed like wheel structure that is known as a sprocket. Basically chains are used to transfer the power transmission from the engine to the gear or to the wheels. It is a very simple, reliable, and efficient method used in machines nowadays.
