ABSTRACT:
A running wheel is slidably supported on a stationary axle between the axle and the bearing bore with a large bearing play and a small Hertzian stress. The axle has a circumferential section which is defined by its sector with a sector angle of less than 180.degree., wherein its radius of curvature is substantially equal to the radius of curvature of the inner wall of the bearing bore. In accordance with the desired bearing play, the radius of curvature of the remaining circumferential section of the axle is smaller than the radius of curvature of the bearing bore. The direction of the main stress acting upon the running wheel lies in the section of the central plane of the axle sector with the larger radius.
