Ultrasonic rotation stages | XRT-U
Compact, fast, precise & durable
This is the XRT-U series. These miniature rotation stages are driven by an ultrasonic piezo motor, offering you the best of both worlds:
1) The lifetime and speed of an electromagnetic motor.
2) The compactness of a piezo stage.
Available as non-magnetic and vacuum-compatible versions, our piezo rotation stages can easily be combined with all of the other Xeryon stages to create multi-axis systems. Enjoy!
Only 1 - 2 weeks lead time for most products.

Compact & precise rotation stage | XRT-U
The XRT-U is a compact and very precise rotation stage driven by an ultrasonic piezo motor. With the XRT-U, you can achieve error motion values close to an air bearing rotary stage, but in a smaller volume and for a lower price.
Compared to other piezo motor technologies, an ultrasonic piezo motor ensures you a non-degrading and vibration-free precision without generating any undesired dither motion during standstill. This makes the XRT-U a state-of-the-art rotation stage for applications such as micro-CT scanners, metrology applications and vacuum and non-magnetic applications, such as electron microscopy.

Non-magnetic rotary stages
All of our rotary & linear stages are available as non-magnetic versions. But what does this mean exactly?
1. Xeryon stages do not generate a magnetic field, thanks to the absence of copper windings or magnets.
2. Xeryon stages can be made without any ferromagnetic materials, making them usable in magnetic fields up to 10T ('Full non-magnetic' option).
For fluctuating magnetic fields, we offer reinforced PEEK plates in order to minimize unwanted eddy current formation.
