Ball Screw Pros. Ball screws offer a high level of mechanical efficiency. Statistics show that ball screws are about 90% efficient, meaning they are able to convert ninetenths of the application's rotational motion into linear motion. In comparison, lead screws have an average mechanical efficiency of just 20% to 25%.
