  • How a Ball Screw Works

    The ball nut determines the load and life of the ball screw assembly. The ratio of the number of threads in the ball nut circuit to the number of threads on the ball screw determines how much sooner the ball nut will reach fatigue failure (wear out) than the ball screw will. C. Ball Nuts Are Manufactured With Two Types of Ball Return Systems
