A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction.A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction.

Ball-screw actuator operation and iterations. Ball screws use a thread form that has a circular shape. The nut has a matched thread form, allowing ball bearings that fit between the grooves to transmit force and relative motion with high efficiency. Ball-screw actuators typically have efficiencies around 80%.

A ball screw, like a lead screw, converts rotary motion into linear motion. The device consists of a threaded shaft and a ball nut. The latter device rides on the screw, supported by a series of ball bearings that provide a rolling surface rather than the sliding surface of a lead screw.

A screw displacement (also screw operation or rotary translation) is the composition of a rotation by an angle φ about an axis (called the screw axis) with a translation by a distance d along this axis. A positive rotation direction usually means one that corresponds to the translation direction by the right-hand rule.Except for φ = 180°, we have to distinguish a screw displacement from its ...
