Ball screw splines from the FB series combine the properties of ball screw drives and anti-rotation shaft guides on a common shaft to offer maximum freedom of movement in a compact stroke-rotation module. Since both the ball screw nut and the ball spline nut can be connected to their own servo motor, complex motion sequences consisting of pure linear motion, pure rotation and also superimpositions of linear motion and rotational motion are possible. An ideal solution for applications where lifting and rotating movements are required, such as pick & place, tool changers and many other applications.
