How does a ball screw actuator work
WebA lead screw is a kind of mechanical linear actuator that converts rotational motion into linear motion. Its operation relies on the sliding of the screw shaft and the nut threads with no ball bearings between them. WebMechanicallinear actuators typically operate by conversion of rotary motion into linear motion. Screw: leadscrew, screw jack, ball screwand roller screwactuators all operate on the principle of the simple machineknown as the screw. By rotating the actuator's nut, the screw shaft moves in a line.
