Rotational connection using a single rolling bearing which is interposed between stationary and dynamic components, and in which a self-aligning or floating seal is used in order to maintain an effective sealing in the event of a misalignment. The rotational connection comprises a sleeve which is mounted on a bearing and on which a line connector can be secured in such a way that the bearing is mounted on the sleeve and fixed, and the components are produced economically, providing a reliable and efficient rotational connection at low cost. <IMAGE>
