WebFeb 1, 2024 · 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 nine-tenths of the application’s rotational motion into linear motion. In comparison, lead screws have an average mechanical efficiency of just 20% to 25%. WebApr 11, 2024 · Rack and pinion drives are used in machine tools, pick-and-place mechanisms, and so forth to provide linear motion of slides, gantries, etc. Sometimes a lead- or ball-screw is preferred, especially for shorter motions, but racks and pinions provide an economical way of achieving long runs.
