Rectilinear motors provide an simple means to convert rotary movement into direct force and displacement. There common versions exist, including screw-type (ball, lead), belt-driven, and hydraulic/pneumatic models. Screw-type actuators are prevalent for their accuracy and relatively compact size, utilizing a spindle that advances or retracts when rotated. Belt-driven versions offer higher speed but may exhibit less precision. Hydraulic/pneumatic options provide substantial force for heavy-duty operations. Applications are vast, ranging from industrial automation (like robotic arms and conveyor systems) to medical equipment (adjusting beds or surgical tables), agricultural machinery, and even home automation projects like adjusting furniture or opening gates. The selection of the ideal actuator depends critically on factors such as required force, speed, precision, and conditions.
