Abstract
A universal-joint cross assembly includes a cross. Four compression rings are mounted at terminal positions of the cross. Each of the four compression rings is positioned at a 90° interval relative to adjacent ones of the four compression rings. The universal-joint cross assembly includes four inner balls. Each of the four inner balls is fixed to one of the four compression rings and forms a portion of a spherical bearing.
