Abstract

A bellows seal (1) on a ball-and-socket joint provided with joint ball and ball pivot (2), especially on a ball-and-socket joint of a chassis bearing, with an elastic bellows has a pivot-side opening and a joint-side opening and axially surrounds the ball pivot (2) of the ball-and-socket joint. A circumferential, elastic and outwardly pointing sealing lip (6), which can be in contact with a sealing surface (7), is provided at the pivot-side opening of the sealing bellows (1). An L-ring, whose first leg (9) points essentially in the axial direction (axial leg) and whose second leg (10) points radially to the outside (radial leg), is provided at the pivot-side opening. The radial leg (10) engages a groove extending on the inside of the sealing bellows (1) or is anchored in it, and the inside of the axial leg (9) is sealingly in contact with an opposite running surface.
