A rotor for an electric motor, comprising a rotor magnet and a bearing for the rotatable support on a fixed axle, the bearing comprising first and second bearing half-shells, wherein at least the first bearing half-shell is moveably arranged within the rotor body with respect to the second bearing half-shell, and wherein the first bearing half-shell is supported against the rotor body by a resilient element tangentially arranged with respect to the axle. The resilient element, at both its side surfaces facing in an axial direction of the axle, has at least one respective first protrusion extending in the axial direction, and the first bearing half-shell, on a side facing away from its bearing surface, includes at least two axially spaced second protrusions each extending in a radial direction and cooperating with the first protrusions for aligning the resilient element.
