ABSTRACT:
Antifriction bearing arrangement for a rotary machine part, especially of the rotor part of an electric motor having its outer winding fastened within the bearing housing, with a shaft mounted in a pair of antifriction bearings whose outer rings are located near the face of the rotary machine part. Said outer rings comprise outer raceways for rolling elements, while the inner raceway is formed directly on the surface of the shaft, the rotary machine part forming with the antifriction bearings an assembly unit whose diameter is less than or at most equal to the diameter of the outer rings of the antifriction bearings, the internal capacity of the bearings corresponding to the amount of grease which is sufficient to maintain lubrication of the bearings over their entire life.
