Key Features

Rotating larger loads with some eccentricity while still meeting great performance? Our RT250AS can do. This rotary stage matches the most stringent requirements with respect to radial and axial error motion, with an excellent tilt stiffness. This product excels by being one of the best stages in terms of load carrying capacity and stiffness for its footprint.
