ABSTRACT:
A center-free large antifriction bearing consisting of two bearing races comprising rolling bearing elements disposed between them and an integrated electrical direct drive in which the rolling bearing elements are disposed on one side of the direct drive, is characterized in that the bearing races (1, 2) engage over each other at the side of the direct drive (7) opposite the rolling bearing elements (3) and have a spacing (20) which is less than the gap (21) between stator (8) and rotor (9) of the electrical direct drive (7), so that contact of stator and rotor is avoided under all operating conditions.
