The invention concerns a rolling device consisting of a bearing and translating ball (1) operating by rotating and pivoting by being lifted in a concave hemispheric body (2) via an orbiting array of microspheres (3) having a dense layer in its northern hemisphere and circulating, through an orbital clearance zone (4) limited by a floating ring (6), in chaotic trajectories under the action of directional and multidirectional movements imparted to the ball (1). The inventive device is particularly useful for handling objects requiring a rolling system.
