ABSTRACT:
A bearing system includes a ball-and-socket joint (1) having an annular spherical body (2) and a congruently shaped, socket-type guide ring (3) for accommodating the spherical body (2), the ball-and-socket joint (1) being radially connected to an elastic annular spring element (4) made of an elastomer material and also being radially connected to a bearing (5); the spring element (4) being connected to a housing (6) on the side facing radially away from the ball-and-socket joint (1); the bearing (5) being able to execute cardanic movements relative to the housing (6); and the facing surfaces (7, 8) of the ball-and-socket joint (1) and housing (6) being always positioned relative to each other in a manner that avoids relative cardanic movements during operation of the bearing system as intended.
