The invention relates to a constant velocity fixed ball joint in the form of a counter track joint, comprising an outer joint part with outer tracks, an inner joint part with inner tracks, torque transmitting balls received in pairs of tracks formed of outer tracks and inner tracks, and a ball cage with cage windows in which the balls are held in a common plane and guided on to the angle-bisecting plane when the joint is articulated. First outer tracks, together with first inner tracks, form first pairs of tracks whose control angles open in a first axial direction. Second outer tracks, together with second inner tracks, form second pairs of tracks whose control angles open in a second axial direction, with the control angles being defined as angles between the tangents at the ball contact points in the tracks when the joint is in the aligned condition. The ball cage comprises a spherical outer face with a greatest diameter. The outer joint part forms an introducing aperture for the ball cage with an aperture diameter D2<D1 between the outer tracks. 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 the 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 with an internal diameter of D3>=D1. A securing element attached at the outer joint part in front of the introducing aperture forms a second stop and guiding face for the spherical outer face of the ball cage.
