摘要

The joint for use in machine tools comprises two ball-and socket-joints (1, 2) arranged one above the other in a housing (7) with the shafts (3, 4) pointing in opposite directions. The balls can be swiveled about two axes at right angles to each other and also rotated about the longitudinal axis of the joint.
