Abstract: A bearing assembly for a driving axle of karts having a tubular housing pivotally supported by a trunnion assembly about a pivot axis which is perpendicular to and lies in a common plane with a longitudinal axis of the tubular housing. Ball bearing assemblies for taking up radial thrust are arranged on opposite sides of the pivot axis and free-wheelingly support a driving axle whose axis of rotation is perpendicular to the pivot axis of the tubular housing. A thrust bearing and thrust washer are arranged between a radial bearing and a support shoulder of the tubular housing provided between the pivot axis and an outboard side of the tubular housing. The trunnion assembly is designed to bring the pivot axis into horizontal alignment. An axial thrust bearing and thrust washer can be provided at both ends of the tubular housing and on opposite sides of the pivot axis. The aforesaid bearing assemblies significantly reduce or eliminate slowdown of the kart due to "chassis bind".
