X R Model available in 6 or 7 axes configuration, is a portable measurement arm designed for different applications of the modern industry. It is the PREMIUM accuracy system offering HI-END performance in any environment.

Accuracy
and repeatability
The X arm operates as a complete stand-alone metrology system, supporting 3D touch probe inspection, digitizing and reverse-engineering.
Compliant with the stringent ISO 10360-12:2016 standard, it ensures consistent and reliable measurement performance.
High-precision encoders combined with an innovative assembly system on every joint, integrating materials such as titanium and carbon composites deliver outstanding accuracy, repeatability, reliability and long-term stability.
Design, portability and usability
The X arm combines a robust mechanical structure with a lightweight design, ensuring ease of use across all 3D inspection tasks.
Its ergonomic design and advanced counterbalance system provide smooth and controlled movement, reducing operator fatigue even during extended use.
SFC (Symmetrical Force Counter-balance) patented system represents the first total ergonomic counter-balance system, giving an effortless experience when using the arm either in a short or prolonged time.
Integrated optical feedback provides clear visual guidance during point acquisition, ensuring accurate operation even in noisy environments where audible feedback may be difficult to perceive.
The Quick-Check monitor allows operators to access key system information in real time, without the need for external devices.
Automatic temperature compensation ensures stable operation without manual adjustments, simplifying the measurement process in any environment.
The hot-swap battery system, batteries can be replaced without stopping the arm, ensuring uninterrupted operation and continuous workflow on the shop floor.
High performance in any environment
It supports multiple configurations, including touch probes, optical probes, laser scanners and laser fork systems for pipe inspection, providing maximum versatility across different applications.
The quick-change probe system, based on the Renishaw® Autojoint® interface, enables fast probe replacement without recalibration.
Thanks to its standard quick mount (3 ½ inches), it can be easily installed on tripods, magnetic bases or custom mobile supports, ensuring stable operation wherever needed.
The X arm is designed to deliver reliable performance across a wide range of working environments.
It maintains consistent performance even in the presence of dust, humidity and temperature variations.
