Case study
RT series & slip ring
More and more rotary stages for CT applications are equipped with a slip ring for an XY sample stage or hexapod. Regularly a rotary union for fluids is added to this.
At LAB Motion Systems we have accumulated a large know-how on the successful integration of sliprings and rotary unions. Integrating them without compromising the precision of the air bearing rotary stage is challenging.
The figure below shows an RT150U rotary stage with a 24 wires slipring for connecting an XYZ stage from a partner. The radial error motion of the complete setup was measured with capacitive probes and the addition of the slipring only increased the radial error motion to 18.5 nm.



“We have extensive know-how on successful integration of slip rings and rotary unions.”
