ABSTRACT:
In order to assure in a simple manner and with the smallest axial mounting space, a low-noise bearing support having little radial unbalance, two axial ball bearings (2, 3) are provided with a firm fit relative to the rotor shaft (1) and mutually braced axially by an interposed spring washer. Advantageously, ball bearing (3) next to the open end face of the bearing hole is designed as a stationary bearing with a press lift between its inner ring (31) and the rotor shaft (1) as well as between its outer ring (32) and the bearing hole.
