A constant-velocity slip ball joint includes an outer joint part with an axis of rotation and outer ball tracks, an inner joint part with inner ball tracks, a plurality of torque-transmitting balls, each guided in associated outer and inner ball tracks, and a cage provided with a plurality of cage windows, which each accommodate each one or more of the balls. The inner joint part can be displaced in relation to the outer joint part by a displacement distance along the axis of rotation. At least a part of the outer ball tracks and at least a part of the inner ball tracks are at a track-helix angle in relation to the axis of rotation. A floor of each ball track, along the displacement path, is spaced apart from the axis of rotation by a respectively constant spacing along a radial direction. A maximum angle of deflection of the inner joint part in relation to the outer joint part is predetermined by an outer contact surface of the cage establishing contact with a first contact surface of the outer joint part and/or by an inner contact surface of the cage establishing contact with a second contact surface of the inner joint part. The cage has a center axis and the inner contact surface is conical. The inner contact surface is at an opening angle of more than 0 degrees in relation to the center axis of the cage.

Constant-velocity slip ball joint

A cage for a constant-velocity ball joint is annular and has cage windows arranged spaced apart from one another along a circumferential direction for guiding balls of the constant-velocity ball joint; wherein each cage window has at least on one side a ball guiding surface facing in an axial direction. The cage can be produced by:
