The ball screw/spline contains the ball screw grooves and the ball spline groove crossing one another. The nuts of the ball screw and the ball spline have dedicated support bearings directly embedded on the circumference of the nuts.
The ball screw/spline is capable of performing three (rotational, linear, and spiral) modes of motion with a single shaft by rotating or stopping the spline nut.
It is ideal for machines using a combination of rotary and straight motions, such as the Z axis of SCARA robots, assembly robots, automatic loaders, and machining center ATC equipment.
