LEUVEN, BELGIUM — In the fast-evolving landscape of high-precision engineering, the demand for smaller, faster, and more accurate motion control systems has never been more acute. Industries ranging from semiconductor manufacturing and advanced photonics to life sciences and aerospace are perpetually pushing the boundaries of miniaturization. To meet these rigorous demands, Xeryon, a renowned Belgian manufacturer specializing in precision piezo motor technology, has officially announced the launch of the XRT-U-35—an ultra-compact rotation stage engineered to deliver unprecedented performance envelopes within severely constrained footprints.
Driven by Xeryon’s proprietary and patented Crossfixx ultrasonic piezo technology, the XRT-U-35 successfully bridges the traditional gap between low-profile housing designs and high-torque output. Measuring a mere 9 millimeters in height and 36 millimeters in width, this innovative motion stage challenges conventional wisdom by packing an impressive 40 mNm (millinewton-meters) of torque into a package that can easily fit in the palm of a hand.
As engineers and system integrators face mounting pressure to deliver complex multi-axis motion in tighter spaces without sacrificing repeatability or reliability, the introduction of the XRT-U-35 marks a significant milestone in motion control innovation.
Main Facts
The XRT-U-35 is not merely a downsized traditional motor; it represents a fundamental reimagining of how rotational motion is generated and controlled at the micro-scale.
At its core, the stage leverages a sophisticated dual-motor configuration powered by Xeryon’s signature ultrasonic piezoelectric elements. This configuration allows the ultra-low-profile housing (9 mm high by 36 mm wide) to exert a continuous and reliable 40 mNm of torque, making it uniquely suited for driving delicate yet demanding optical and mechanical assemblies.
One of the most striking technical achievements of the XRT-U-35 is its dynamic velocity range. The stage is capable of executing ultra-smooth, highly controlled rotation speeds adjustable from a glacial 0.01°/s all the way up to a rapid 1,080°/s. Crucially, it achieves this wide performance spectrum without the use of gearboxes or additional mechanical transmissions. By eliminating gears, Xeryon has successfully eradicated backlash, mechanical slop, and transmission-related inaccuracies that typically plague traditional micro-positioning stages.
Furthermore, the ultrasonic piezo drive architecture brings inherent material and operational advantages:
- Zero Magnetic Fields: Completely non-magnetic operation makes the stage ideal for sensitive environments such as electron microscopes, particle physics laboratories, and magnetic resonance testing setups.
- Wear-Free Operation: With no internal components subject to friction-driven mechanical wear, the service life of the XRT-U-35 is rated at over 10 million revolutions, drastically reducing maintenance overhead and system downtime.
- Self-Locking Position Hold: When power is cut to the unit, the piezo elements instantly act as a secure, self-locking brake, holding the position with absolute integrity without drawing electrical current.
- Through-Hole Architecture: The stage features an 8 mm H7 central aperture, allowing engineers to route critical infrastructure—such as electrical wiring, optical fibers, or laser beams—directly through the axis of rotation, vastly simplifying system integration.
Chronology of Development: From Concept to Commercialization
The genesis of the XRT-U-35 is rooted in years of intensive research and development at Xeryon’s advanced engineering facilities in Belgium. Understanding the chronology of this product highlights the methodical approach the company took to disrupt the traditional motion control market.
Phase I: The Evolution of Crossfixx Technology
Long before the conceptualization of the XRT-U-35, Xeryon identified the limitations of conventional electromagnetic motors at sub-millimeter scales. Electromagnetic motors suffer from thermal constraints, backlash, and the need for bulky gear reductions when miniaturized. Xeryon’s engineers pivoted toward ultrasonic piezoelectric technology, culminating in the development and patenting of their Crossfixx technology. This proprietary drive principle utilizes high-frequency vibrations to push a runner along a precise trajectory, offering nanometer-scale resolution and instantaneous response times.
Phase II: Prototyping and Ultra-Miniaturization (2024–2025)
As industries increasingly demanded flat, low-profile stages that did not compromise on torque, Xeryon’s R&D department initiated the "XRT-U" project family. The primary challenge was marrying the high-force output required for industrial applications with a housing thickness of under 10 mm. Through iterative computer-aided engineering (CAE) simulations and advanced thermal management studies, the team finalized the dual-motor layout that would eventually become the hallmark of the XRT-U-35.
Phase III: Rigorous Testing and Reliability Validation (Late 2025–Early 2026)
Before bringing the stage to market, prototypes underwent rigorous durability and precision benchmarking. Engineers subjected the XRT-U-35 to continuous cycling tests, verifying that the piezoelectric elements could comfortably exceed the 10-million-revolution service life milestone without degradation in step accuracy or torque output.
Phase IV: Official Market Launch (August 2026)
In August 2026, Xeryon officially unveiled the XRT-U-35 to the global motion control community. Positioned as a flagship addition to their rotation stage portfolio, the product instantly captured the attention of design engineers seeking out-of-the-box solutions for ultra-compact, high-precision automation tasks.

By integrating a clean, unobstructed central bore, Xeryon has eliminated this engineering headache entirely.
Official Responses and Industry Perspectives
The release of the Xeryon XRT-U-35 has elicited strong reactions from industry analysts, automation experts, and internal engineering leadership alike.
In statements accompanying the product launch, Xeryon’s technical leadership emphasized that the stage was built in direct response to customer frustrations regarding the compromises inherent in legacy motor systems.
"For years, engineers designing miniature optical setups or high-precision inspection tools have had to make an agonizing choice," noted a representative from Xeryon’s engineering division. "They could choose a low-profile stage that lacked the torque to drive payloads reliably, or they could use a robust motor system that completely ruined their space and weight budgets. With the XRT-U-35, we have eliminated that compromise. By scaling our patented Crossfixx ultrasonic technology into a 9-millimeter-high housing, we are giving creators 40 mNm of direct-drive torque with zero backlash and absolute positional security."
Independent motion control specialists have echoed these sentiments, pointing out that the elimination of gearboxes is a major victory for system longevity. Traditional gear trains are frequent points of failure due to mechanical wear and lubrication breakdown over time. Because the XRT-U-35 relies on frictionless ultrasonic surface interactions, it bypasses these failure modes entirely, a feature that field application engineers are expected to welcome enthusiastically.
