DVD drive with leadscrew and stepper motor.
Floppy disc drive with leadscrew and stepper motor.
A mechanical linear actuator with digital readout (a type of micrometer).
A miniature electromechanical linear actuator where the lead nut is part of the motor. The lead screw does not rotate, so as the lead nut is rotated by the motor, the lead screw is extended or retracted.
