A machine pulley is used in an industrial, automotive, commercial, or manufacturing machine. Any type of machine pulley, whether used in an engine crankshaft, a conveyor belt, or bicycle gears, is derived from the simplest forms of pulley systems.
A machine pulley is comprised of one free spinning wheel on an axle with a belt, chain, cable or rope running over that wheel. One purpose of a machine pulley is for easing the total amount of work it takes for lifting loads, which is known by the term “mechanical advantage.” An array of different machine pulley types are used to operate a variety of machines.
