Abstract: A bearing for substantially vertical shafts rotated at high speeds by electric motors or the like utilizes a spherical thrust bearing at the lower end of the shaft with an elastic radial bearing mounted on the upper portion of the shaft. The upper radial bearing comprises a magnetic radial bearing having a plurality of polarly magnetized annular or disc-like inner rings mounted adjacent to each other on the shaft and a plurality of polarly magnetized annular or disc-like outer rings separated from the inner rings by an air gap. The inner and outer rings are magnetically so disposed that they repel each other and thereby stabilize the shaft in the radial direction. An annular bearing member is also provided to cooperate with the magnetic radial bearing to prevent damage to the magnetic bearing because of excessive deflection of the shaft from its vertical position during the initial start up of the shaft.
