For higher loads up to 80 kg, the RT250S completes the LAB RT-S series. 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.
LAB’s RT-S series is your go-to choice when looking for rotary air bearing stages with superior error motion performance, high stiffness and high load-carrying capacity! The low-profile design of the RT-S series houses a top-class air bearing, motor and encoder which enable excellent angular positioning and velocity stability. A large through hole facilitates slip ring integration, optical or other feedthrough for specific applications such as x-ray and optical inspection.
This rotary stage can be supplied with motion driver and software. The software offers an easily programmable positioning loop, automatic homing procedure and communication with your machine interface. An emergency procedure to generate a safe stop when pressure supply fails is integrated. Additionally, a graphical user interface decreases the setup-time to a minimum.
