Ball screws are used in electric fly-by-wire and in automotive power steering systems to convert the rotational motion of the motor into the axial motion of the steering rack. Small, lightweight and highly reliable ball screws High-precision ball screws are used in steppers in semiconductor manufacturing. They are also used in machine tools, robots and precision assembly equipment. Ballscrew used the ball movement, so the starting torsion is very small, doesn't appear a sliding motion creeping phenomenon.
