Thermally compensated mounting assembly with a monolithic mounting element and with a rotationally symmetrical element mounted therein, wherein the mounting element is divided into a mounting ring with an axis of symmetry and a plurality of elastic connection arms via which the mounted element is held in the mounting element. The connection arms have at least one portion which extends in axial direction of the axis of symmetry. A compensation ring contacts all of the connection arms inside these portions coaxial to the mounting ring. The compensation ring is advantageously made from the same material as the mounted element and completely absorbs the restoring forces occurring as a result of the temperature-dependent deformation of the connection arms due to a different expansion of the mounting element and of the mounted element so that invariant forces act on the connection points between the connection arms and the mounted element.
