A switchable bearing is disclosed which comprises a cup-shaped housing sealed by an annular spring element of an elastomeric material. Between the spring element and the housing base is a separating wall, which has at least one flow-through opening and which, together with the spring element, delimits a working chamber and, together with the housing, delimits a compensating chamber. The working chamber and the compensating chamber communicate through the flow-through opening and are filled with a hydraulic fluid. The flow-through opening is sealed by a piston of a control unit, arranged at least partially in the compensating chamber. The piston is actuated by a pressurized medium, and is connected in a gastight and relatively movable manner to an aneroid chamber, which is rigidly mounted in the housing and is capable of being charged with a pressurized medium. The aneroid chamber is delimited by a flexible first ring diaphragm, which seals off the piston and the aneroid chamber from the housing.
