Xeryon, a prominent Belgian manufacturer renowned for its advanced precision piezo motor technology, has officially unveiled the XRT-U-35, an ultra-compact rotation stage engineered to meet the stringent demands of high-precision positioning systems across a diverse array of industries. This latest innovation integrates Xeryon’s proprietary Crossfixx ultrasonic piezo technology, seamlessly blending a remarkably low-profile housing with an impressive 40 mNm of torque output, setting a new benchmark for performance in miniaturized motion control solutions.
The Dawn of Precision: Xeryon’s Latest Innovation
The introduction of the XRT-U-35 signifies a pivotal advancement in the field of precision motion control, particularly for applications where space is at an absolute premium. The stage boasts an exceptionally compact form factor, measuring a mere 9 mm in height and 36 mm in width. Despite its diminutive size, the XRT-U-35 is equipped with a sophisticated dual-motor configuration that collectively delivers a robust 40 mNm of torque. This substantial torque capability is crucial for accurately and reliably driving a variety of optical and mechanical assemblies, from intricate lens systems to complex micro-manipulators.
Beyond its power-to-size ratio, the XRT-U-35 offers unparalleled rotational control. Its speed is precisely adjustable, ranging from an exceptionally slow 0.01°/s to a rapid 1080°/s. A key differentiator of this stage is its ability to achieve this broad speed range without relying on conventional gearboxes or additional mechanical transmission components. This design choice inherently eliminates backlash, reduces friction, and enhances the overall precision and repeatability of movements, which are critical factors in sensitive scientific and industrial applications.
Unpacking Crossfixx Technology: The Heart of the XRT-U-35
At the core of the XRT-U-35’s remarkable performance lies Xeryon’s patented Crossfixx ultrasonic piezo technology. Piezoelectric motors operate on a fundamentally different principle than traditional electromagnetic motors. They convert electrical energy directly into mechanical motion using piezoelectric materials that expand and contract when an electric field is applied. Ultrasonic piezo motors, in particular, utilize high-frequency vibrations to drive a moving element, offering several distinct advantages over conventional motor technologies.
The Crossfixx technology employed in the XRT-U-35 exemplifies these benefits. Firstly, the ultrasonic piezo drive generates no magnetic field, making it an ideal choice for applications sensitive to electromagnetic interference (EMI). This is particularly relevant in environments such as electron microscopy, MRI equipment, or in close proximity to sensitive sensors where magnetic fields could compromise data integrity or system performance. Secondly, the absence of gears and internal components subject to mechanical wear drastically improves the stage’s reliability and longevity. Traditional geared systems often suffer from wear and tear, leading to reduced precision over time and requiring frequent maintenance. By eliminating these elements, the XRT-U-35 promises a significantly extended service life, rated above an impressive 10 million revolutions, reducing total cost of ownership and maximizing operational uptime.
Furthermore, the design supports exceptionally quiet operation and low vibration levels. This characteristic is invaluable in environments where acoustic noise or mechanical vibrations could interfere with experimental results, image acquisition, or operator comfort, such as in laboratory settings, medical diagnostic rooms, or high-precision manufacturing facilities. Another significant advantage of the piezo drive is its self-locking position hold feature. When power is removed, the stage inherently maintains its last commanded position, providing crucial stability and safety without the need for additional braking mechanisms. This "power-off hold" capability is a critical safety feature and ensures process integrity during power interruptions.
Integrated Design for Seamless Engineering
Thoughtful engineering is evident in the XRT-U-35’s integrated features, designed to simplify its incorporation into complex systems. A practical 8 mm H7 central aperture runs through the axis of the stage. This through-hole design is a significant advantage, allowing engineers to route essential cables, optical fibers, or even laser beams directly through the center of rotation. This capability not only streamlines system integration by reducing cable management complexities but also ensures that critical connections remain untangled and protected, especially in multi-axis setups or systems requiring continuous rotation. This feature can drastically simplify the design of compact optical setups, end-effectors for robotic systems, or intricate scientific instruments where minimizing footprint and maximizing functionality are paramount.
Engineering Miniaturization: Addressing Industry Demands
The global push towards miniaturization across high-tech sectors has created an escalating demand for motion control components that combine high performance with an ultra-compact footprint. Industries ranging from semiconductor manufacturing to medical diagnostics, and from advanced photonics to scientific research, are consistently seeking smaller, more precise, and more reliable components to enable next-generation devices and processes. Traditional motor technologies often struggle to deliver high torque and high precision within extremely confined spaces without significant compromises in performance, lifespan, or operational characteristics like noise and heat generation.
The XRT-U-35 directly addresses these evolving industry requirements. Its ability to deliver 40 mNm of torque within a 9×36 mm envelope represents a significant technological leap. Engineers working on miniaturized systems often face the daunting challenge of balancing mechanical space constraints with the need for robust motion capabilities. The XRT-U-35’s compact form factor and standardized mechanical interface make it uniquely suitable for applications where installation space is severely limited, yet precise and powerful rotational motion is indispensable. This innovation allows for the development of smaller instruments, more densely packed experimental setups, and more agile robotic systems, pushing the boundaries of what is possible in miniaturized engineering.

The XRT-U-35’s fine angular resolution and vibration-free operation make it ideal for adjusting mirrors, lenses, filters, and fiber optics with sub-micron accuracy, ensuring optimal light path integrity and performance.
- Microscopy and Scientific Instrumentation: Advanced microscopy techniques (e.g., atomic force microscopy, super-resolution microscopy) and other scientific instruments often require precise sample manipulation or component positioning within a confined stage area. The XRT-U-35’s low vibration, quiet operation, and central aperture for illumination or sensing pathways are invaluable for these sensitive applications.
- Semiconductor Manufacturing and Inspection: The fabrication and inspection of semiconductor wafers demand extreme precision and repeatability. The XRT-U-35 can be integrated into wafer handling systems, inspection platforms, or lithography equipment where its non-magnetic properties and long service life contribute to higher yields and reduced downtime.

The XRT-U-35’s ability to operate without magnetic interference and its high torque-to-size ratio make it an excellent candidate for robotic surgery, micro-fluidic handling, or medical imaging systems.
- Photonics and Laser Systems: For applications involving laser scanning, beam steering, or optical switching, the XRT-U-35 offers the necessary precision and dynamic range. Its through-hole design is particularly beneficial for routing laser beams directly through the rotation axis, simplifying complex optical designs.
- Robotics and Automation (End-Effectors): As industrial and collaborative robots become smaller and more dexterous, there is a growing need for compact, high-precision motion components for end-effectors, grippers, and inspection tools. The XRT-U-35 can provide precise wrist rotation or tool articulation in tight spaces.
