A mechanical press drive that uses a ballscrew apparatus to move the upper platen of a press upward and downward. A first coupling is connected to a screw of the ballscrew apparatus and connects the screw to one of a movable platen of a press or a stationary member of the press. A second coupling is connected to and couples a nut of the ballscrew apparatus to the other of the platen and the stationary member of the press. A drive motor is operably connected to one of the nut and screw and relatively rotates them to impart reciprocal motion to a movable press platen coupled to the other of the nut and screw. The two couplings cooperatively isolate the ballscrew apparatus from offset and moment loading that may occur during press operation.
