This Ball Spline video is presented to clarify the difference between Ball Screw Splines and Ball Splines. The Ball Spline nut, as you will see in the video, travels along the shaft using its straight grooves as the guides for the rolling elements. Not seen in the video are Ball Screw Splines that have some nuts that travel using the straight grooves as rolling element guides and some nuts that spiral on the shaft.
