Ball Screws
How a Ball Screw Works
A. The Ball Screw AssemblyThe ball screw assembly consists of a screw and a nut, each with matching helical grooves, and balls which roll between these grooves between the nut and the screw when the nut or screw is rotating. The balls are deflected by the deflector into the ball return system of the nut and they travel through the return system to the opposite end of the ball nut in a continuous path, and exit from the ball return system into the ball screw and nut thread raceways continuously to recirculate in a closed circuit.
