A constant velocity fixed joint has an outer part 1, an inner part 9, a cage 18 and balls 23 which are guided by the cage 18 in the outer running grooves 5 of the outer part 1 and in the inner running grooves 14 of the inner part 9. The inner part 9 is held relative to the outer part 1 entirely by the balls 23 in the radial direction and by the ball 23 on the one hand and by a control element 24 on the other hand, which control element 24 is supported on the inner part 9 and on a supporting element 35 associated with the outer part 1. Beyond the advantageous supporting conditions achieved by said assembly, it is possible to achieve a further reduction in friction by friction-reducing means which are provided in the form of lubricating grooves 31, 33 for example, thus achieving hydro-dynamic lubrication conditions which are advantageously affected in that the control element 24 achieves high sliding speeds relative to the supporting element 35.
