A hydraulically damping rubber bearing comprising an inner supporting body surrounded with radial clearance by an outer supporting body. The inner and the outer supporting bodies are joined together by a resilient elastomeric element forming the boundary of a working chamber filled with damping fluid. The working chamber is separated from a compensating chamber by a separating wall having at least one duct-shaped opening and is connected to the compensating chamber in a manner such that it is in fluid communication with it. The compensating chamber is sealed on the side facing away from the separating wall by a compensating membrane. The separating wall has a centrally arranged opening which surrounds the inner supporting body with radial clearance, the annular gap formed by the clearance being designed as a damping duct. The separating wall also has at least one window filled in by a window membrane made of elastomeric material to isolate higher frequency vibrations.
