A device formed by a spindle is connected to a nut and to one or more servo motors where the transmitted torque will be the sum of the separate torques of the servo motors. The device has a set of two or more rods arranged around the spindle. The spindle is supported in two bearing housings that restrict axial movement in both directions, including an anti-reverse system that only allows a drive shaft to rotate, all inside an inner sleeve. An outer sleeve moves along the outside of the inner sleeve under a fixed metal structure for securing to a machine, keeping all particle entry units closed. Four screwed elements allow the spindle to be put into a parked position to facilitating replacement of wear units.
