1. An electric axle drive comprising:
a rotor shaft having a first groove;
a first circlip engaged in the first groove;
a first securing sleeve having a first portion axially fastened on the rotor shaft and a second portion extending radially over the first circlip to prevent release of the first circlip due to centrifugal forces when the rotor shaft rotates; and
a first bearing having a first inner ring axially positioned with respect to the rotor shaft by the first circlip.
