ABSTRACT:
Rotor assembly comprises a rotor and a bearing having inner and outer races with rolling elements disposed therebetween, one of the races being secured to the rotor and the other thereof being secured to a rotatable annular member concentric with the rotor. Magnetic means secured to each of the races cooperate to take up the axial clearance of the bearing, reducing it to virtually zero.
