A design of a bush bearing with hydraulic damping for achieving an axial seal for the chambers receiving the viscous damping means. The bearing is designed with an axial seal that reliably prevents the damping means from leaking out of the bearing as well as air from entering the bearing. In the bearing, the damping means chambers are sealed in a conventional manner by axial sealing lips, which are preferably formed by regions of the elastomer bearing body having an outer diameter that is greater than the inside diameter of the outer sleeve. One or several volumes are arranged in the region of the sealing lips, wherein the volumes extend at least along sections of the periphery of the bearing body and are not in fluid communication with the damping means chambers. The volumes are filled with a viscous fluid having a pressure that is essentially equal to or higher than the ambient pressure, but is always higher than the pressure in the damping means chambers.
