A lead screw can be a type of mechanical linear actuator that transforms rotational movement into linear movement. It operates from the sliding conversation involving the screw shaft and the nut threads, without the utilization of ball bearings.
Thread: The thread is the composition responsible for changing rotational movement into linear motion as the screw shaft along with the nut slide with one another.
