A bearing arrangement for the rotor of a rotating machine, in particular of a hydrogenerator rotating about a vertical axis, comprises a combined axial and radial bearing which is accommodated in a bearing body, on which supporting arms are arranged for absorbing axial forces. The supporting arms are supported with the free ends on a load-bearing base. Tangentially oriented connecting elements are additionally provided between the bearing body and a foundation, enclosing the rotor, for absorbing radial forces and for centering the bearing, which connecting elements are fastened at a first end to the foundation and are fastened at a second end to articulation points arranged directly on the bearing body. This results in a material-saving construction, optimization of the individual bearing functions, and improved adjustability.
