Ball Bearing Rotary Stage

The ball-bearing stage RT150B features a design for your precision rotary needs, with radial and axial error motions below 1 µm. It provides the optimal solution in case you are looking for a rotary stage with high load-carrying capacity in a compact design, without the need for a conditioned air supply. LAB’s RT150B serves as an ideal partner for your entry-level metrology applications where sub-micron accuracy is required.

RT-B Series

The RT-B series is the optimal solution when you are looking for a robust rotary stage, without the need for a conditioned air supply! These ball bearing stages combine a high load-carrying capacity with a compact design. They provide you with a dynamic, disturbance-free drive, ready to serve any application! High-quality ball bearings ensure that the radial and axial error motions remain below 1 µm. Furthermore, LAB’s RT-B series is easily integrated in any system or setup and can be equipped with MK2 conical mounts upon request.

Motion Control

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.
