Patent ID: 7909313

Claim:
An elastomer bush bearing comprising a metallic inner part having a circular or elliptical cross-sectional area and a through opening having a uniform diameter extending in an axial direction through the inner part, a cylindrical outer sleeve surrounding the inner part, and an elastomer bearing body having axial end faces, said bearing body disposed between the inner part and the outer sleeve and adheringly connected at least with the inner part by vulcanization, wherein the cylindrical outer sleeve terminates at its axial ends in a corresponding circumferential flange oriented in the direction of the inner part, wherein each of the axial end faces of the bearing body comprises an undulated contour having wave troughs and wave crests, with the wave troughs and wave crests of one end face facing corresponding wave troughs and wave crests of the other end face, said contours being formed in the bearing body in the circumferential direction in the same direction and over a total material thickness of the bearing body, and an axial height of the bearing body along the axial direction varies continuously in the circumferential direction without formation of abrupt steps, and wherein the elastomer bush bearing further comprises means for marking at least one circumferential position of the bearing, wherein the elastomer bush bearing further comprises means for marking at least one circumferential position of the bearing, and wherein the means for marking comprise a groove formed on an inner surface of the inner part which surrounds the through opening, wherein the groove extends from one of the axial end faces in the axial direction towards an inside portion of the bearing or to the other end face.
