An elastomer bush bearing, wherein the bearing body () is encapsulated through axial flanges () of the outer bearing sleeve (), with the bush bearing having an elastomer bearing body () with a special profile in the axial direction. The bearing body () is employed in constructing the bush bearing of the invention, which is capable of supporting high radial loads even with low radial stiffness and without adversely affecting its stability and service life. The two axial end faces () of the bearing body () each have undulated contours which extend in the circumferential direction (u) in the same direction, both with respect to one another and also over the entire region of the material thickness (d) of the bearing body (). The end faces () of the bearing body () thus have wave troughs () and wave crests (), whereby the corresponding wave troughs () of both end faces () and their wave crests () are formed so as to face one another, and each extend radially over the entire material thickness (d) of the bearing body () in the respective circumferential segment.

A bush-type rubber mount is provided, preferably a hydraulically damping rubber mount, with a, preferably tubular, metallic inner part, an elastomeric mount body surrounding the inner part and connected to it by vulcanization. An outer sleeve accommodates the inner part. The inner part has, in an axial section, two radially outwardly extending elevations located opposite each other on its circumference and are completely embedded in the elastomer. Two elastomer recesses extend in a kidney-shaped pattern in relation to the circumference of the mount body between the elevations and pass axially through the mount body. The two elastomer recesses are arranged in the elastomeric mount body near the inner part, so that the inner part standing free in relation to the outer sleeve in the area of the kidneys is connected to the mount body essentially only via the elevations on the mount body. A defined cardanic axis extending through the apices of the elevations is formed at right angles to the axis of the mount.
