Abstract

A counter track joint including first pairs of tracks whose control angles open in a first axial direction, and second pairs of tracks whose control angles open in a second axial direction. The outer joint part forms an introducing aperture for the ball cage. The ball cage, while engaging the outer tracks, can be threaded into the outer joint part in the second axial direction. The outer joint part forms a first stop and guiding face for a spherical outer face of the ball cage. Between the introducing aperture and the first stop and guiding face, the outer joint part comprises a displacement region for the ball cage. A securing element forms a second stop and guiding face for the spherical outer face of the ball cage.
