1. A screwdriving system for connection of components that require high contact pressures for their screw connection, the screwdriving system having a screwdriving unit which is connected to an articulated robot, wherein the screwdriving unit contains a motor for a rotary drive, an actuator for a linear drive, a gear mechanism, a torque shaft, a tool holder for a screwdriving tool and a feed head which is supplied with screws which are held in the feed head during the screwing-in operation, the tool holder, the screwdriving tool and the feed head being arranged on a common screw axis, the screwdriving system comprising:
an articulated bearing arrangement, the pivoting of which is able to compensate for a deflection of a robot axis of the articulated robot caused by contact pressures and for a tilted position of the screwdriving unit resulting therefrom.
