Acoem NXA Pro, A Revolution in Shaft Alignment with Enhanced Benefits

Step into a new era of shaft alignment with the Acoem NXA Pro – a cutting-edge digital laser-based system that sets a new standard in usability!


Acoem NXA Pro is the most user-friendly and cost-effective laser alignment system in the industry.

The Acoem NXA Pro not only revolutionizes shaft alignment but also elevates the user experience with our advanced GuideU™ interface. This intuitive system ensures lightning-fast and straightforward operations while granting access to exceptional features. Moreover, it boasts one of the most robust power management systems on the market.

But that’s not all. When you choose the Acoem NXA Pro, you also enjoy the peace of mind that comes with a lifetime warranty and a comprehensive system. Experience the future of shaft alignment, elevated by GuideU™ and backed by our commitment to quality.

Alignment Intelligence

The NXA Pro system represents over 30 years of laser-based shaft alignment innovation. Through Alignment Intelligence, maintenance professionals can do their jobs more efficiently and achieve better results.


Adaptive User Interface for Smart Sensors

You will be guided through the measurement and alignment process of your machines using the adaptive user interface of the  NXA Pro.


The graphical user interface is shown off on a 6,5” transreflective display screen with icons and symbols to guide you, in other words, no text is involved.

The adaptive user interface will guide you throughout the measurement and alignment process.

We have fitted the NXA Pro with gyros and can, therefore, adapt the screen view from the same side that the user is positioned – our OmniView™ function, i.e. the system knows where it is in relation to the machine.

VertiZontal Moves™

The adaptive user interface will guide you throughout the measurement and alignment process. We are especially proud of the function – VertiZontal Moves™ – where you only have to measure once before making the required vertical and horizontal adjustments. Quite a time conserver in a time-strained maintenance world!




Power management system

The NXA Pro has a power management system that will make your life so much easier! The display unit has a 10 hour continuous battery operating time, and should the need arise during an alignment job; the display unit can be express charged to an 80% capacity in one hour. The sensor units will last for 24 hours minimum thanks to the long-life batteries.


Time-saving technology

The NXA Pro’s sensor units have graduated to the 2nd generation sensor. This sensor version improves the tolerance for detrimental external factors, such as vibrations and ambient light, and delivers the most accurate and precise measurement values compared to any other system. Measurement values are automatically registered throughout the entire measurement process. We have integrated line laser with the sensor and this combination virtually eliminates rough alignment, a huge time saver.

Very compact, only 33,5 mm in width, the sensor units will fit in the tightest spots. The sensor units contain long-life batteries, Bluetooth communication, and gyroscopes. The gyroscopes make it possible to measure according to the Tripoint Method in the vertical shaft alignment application, something that no other shaft alignment instrument is capable of!

Our interface uses a game-like 3D graphic look to give the user a clear understanding of any misalignment errors. Measurement reports generated by our icon-driven, language-free alignment systems are easy to understand by everyone, regardless of their native language.

Limited Lifetime Warranty

​The NXA Pro has a limited lifetime warranty. For more information, contact your local dealer!
