Ball Bearing Sprocket Ball is a type of sprocket that uses ball bearings to reduce friction between the sprocket and the shaft it rotates on. This helps to increase the efficiency of power transmission and reduce wear and tear on the components. Ball-bearing sprockets are commonly used in industrial equipment, such as conveyor systems, as well as in various types of machinery and vehicles. The use of ball bearings in sprockets helps to ensure a smooth and reliable operation, even under heavy loads and high speeds.
