Abstract
A high-precision, low backlash linear actuator drive mechanism characterized by minimal positional repeatability error irrespective of the direction from which a selected or target position is approached may comprise a bellows coupling operative to transmit rotational motion from a motor to a drive spindle. Rotation of the drive spindle causes linear translation thereof in an axial direction.
