Sprockets and Pulleys Manufacturers

Sprockets are gear with metal teeth that meshes with a chain or track. These are used in bicycles, motorcycles, cars, tanks, and other machinery. These are also used in the film transport mechanisms of movie projectors and movie cameras. In this case, the sprocket wheels engage film perforations in the film stock. A pulley is a wheel with a groove along its edge. These are usually used to change the direction of an applied force or in sets designed to reduce the amount of force needed to lift a load.
