This invention provides a linear driving mechanism having a housing, front and rear covers fixed at opposite ends of the housing, a stator arranged inside the housing, and a hollow rotor arranged inside the stator, driven by the stator to rotate. The linear driving mechanism further includes a rolling lead screw fitted inside the rotor, a first bearing, and a second bearing. The rolling lead screw includes a central screw rod and a screw nut. The screw nut is fixedly sleeved around the inner peripheral side of the rotor near the front cover. The linear driving mechanism of the present invention can enhance the integration of the rolling lead screw and rotor to reduce the volume space of the linear driving mechanism, meeting the demand for miniaturization.
