Abstract

A ball and socket joint (1) is provided, for example, for a chassis bearing, with a ball (2), a pivot (3) originating from the ball (2), a housing (4) accommodating the ball, and a sealing bellows (5), which extends between the housing (4) and the pivot (3) and has a housing-side opening (6) and a pivot-side opening (7). The sealing bellows (5) has a circumferential sealing lip (8) for sealing at the pivot-side opening (7). The ball and socket joint (1) has a first guide ring (9), which guides the sealing bellows (5). The first guide ring (9) is arranged at the pivot (3). An especially favorable functional separation is achieved as a result between the guiding function and the sealing function.
