Abstract: A disc style cross groove universal joint including an outer joint member open on front and back sides having a plurality of inward facing outer ball grooves and an inner joint member inside of the outer joint member having a plurality of outward facing inner ball grooves. The inner and outer ball grooves define crossed pairs having a bearing ball therebetween. In a center position of the inner joint member in the outer joint member, the bearing balls are evenly angularly spaced. A cage has a plurality of windows for the bearing balls. An outboard side edge of each cage window is separated from the center of the bearing ball therein by a long span dimension in the center position of the inner joint member. An inboard side edge of each cage window is separated from the center of the bearing ball therein by a short span dimension in the center position of the inner joint member.
