Wobble bearing, in particular for producing a searching movement of a radar antenna. A yoke having first annular magnets (6) in the shape of a zone of a sphere and comprising permanent magnets are installed in a housing (1, 2). Mounted in the yoke is a rotor (3) on which are seated second annular magnets (5) in the shape of a zone of a sphere and comprising permanent magnets. At their mutually opposite faces, the first and second annular magnets (6, 5) have the same polarity, i.e. repel each other. The rotor (3) has a disc-shaped part (13) which extends beyond the bearing and in which first driving ferrites (12) are embedded at suitable points on the circumference. Second driving ferrites (10) controllable by means of driving coils (11) are embedded in the housing (1, 2), opposite the first driving ferrites (12) (Fig. 1). <IMAGE>
