Ball screwAppliions. Ball screws are used in aircraft and missiles to move control surfaces, especially for electric fly by wire, and in automobile power steering to translate rotary motion from an electric motor to axial motion of the steering rack. They are also used in machine tools, robots and precision assembly equipment. High precision ball screws are used in steppers for semiconductor ...
When do you need a ball screw? · Below are four common appliion criteria that (in most cases) require a ball screw. Heavy loads. With recirculating steel balls to support the load, ball screws have a higher load capacity than comparably sized lead screws with plastic or polymer nuts. Lead screws with bronze nuts can drive heavier loads, but as the load increases, so does ...
