ABSTRACT:
An actuating device for an electric switching apparatus comprises a shaft as well as a tube which contains the bearings of the shaft, for instance, roller cages. The tube has lathe cuts which engage in openings in the walls and is thereby fixed in the axial direction. An alignment tolerance of the openings in the walls does not affect the properties of the bearing adversely.
