摘要： A dynamic bearing with an improved thrust bearing and a beam deflecting apparatus employing the same are disclosed. The dynamic bearing includes a bearing housing having a hollow cavity. A shaft is provided in the hollow cavity so that the shaft can rotate with respect to the bearing housing. First and second magnets are disposed at one end of the shaft and the hollow cavity, respectively. The first and second magnets are spaced a predetermined gap from each other and face each other. The first and second magnets generate a magnetic, repulsive force and support the shaft, without contact, in the axial and radial directions. The dynamic bearing may be used in a beam deflecting apparatus. In that case, a driving source is installed, in parts, on the bearing housing and the rotating shaft. The driving source drives the rotating shaft to rotate by electromagnetic force. A beam deflecting device is installed on the rotating shaft for deflecting an incident beam and performing a scanning operation.
