• a housing comprising a first base plate, a second base plate and at least three columns arranged between the first and second base plates, wherein the columns connect the first and second base plates to one another and keep them spaced apart, wherein a first opening is arranged in the first base plate and a second opening is arranged in the second base plate,
• wherein at least a part of the motor is arranged on a first side of the first base plate facing away from the columns and at least a part of the press ram is arranged on a second side of the second base plate facing away from the columns, and wherein the motor and the press ram are interconnected through the first opening and the second opening,
• wherein the press ram protrudes through the second opening out of the second base plate, and wherein a press plunger is arranged at an end face of the press ram or the press plunger is formed by the end face, the end face being disposed on the second side of the second base plate,
• wherein the drive train further comprises a spindle drive having a spindle and a spindle nut,
• wherein the spindle drive comprises a component which is rotationally driven by the motor and a translationally moved component which is coupled to the rotationally driven component and which is translationally guided and secured against rotation on at least one of the at least three columns by means of a guide, wherein either (i) the spindle is the rotationally driven component and the spindle nut is the translationally moved component, or (ii) the spindle is the translationally moved component and the spindle nut is the rotationally driven component,
• wherein the guide comprises a bearing, and
• wherein the bearing comprises two rollers which are configured to roll on the at least one of the at least three columns, wherein the two rollers are each connected to the translationally moved component.
