Easy-Laser® XT440 is a member of our Generation XT alignment systems, built upon our new cross-platform technology. This means you will be able to display data on a multitude of different handheld devices, including our own XT12. With XT440 you can carry out the following:

  • ​Align the machine.
  • Check soft foot.
  • Document and share the results.

With Easy-Laser XT440, you can perform all necessary steps of shaft alignment on horizontal and vertically/flange mounted machines. The user-friendly software, available in ten languages, guides you step by step through the measurement process. ​

Use the system together with the rugged Easy-Laser XT12 display unit or install the free XT Alignment app on your iOS or Android device*. Whatever you choose, the intuitive user interface is the same across all platforms.

The measuring units and XT12 display unit are shockproof and rated both IP66 and IP67 water and dustproof. Along with long operating times, this guarantees you will be able to take on and finish even the toughest jobs. 

Unique documentation possibilities 

From the app, you can easily create and share a PDF report containing all measurement data and images. If you use the XT12 display unit, it has a built-in 13MP camera. The XT12 can also be equipped with an IR camera, which allows you to add a thermal image of the machine before and after alignment.


"This new system is very straightforward and easy for new mechanics to learn and work with. Unlike our old system, the XT440 is completely wireless which is handy. And since it’s quick to set up and use we are now able to align machines much faster. This minimises downtime for our clients and saves them money. Also, it frees time from our mechanics"

Measurement programs

The featured programs below are the most commonly used with this system. Please click here for a complete overview of possibilities.
*=accessories needed

Horizontal machines

The user interface is intuitive and guides you through the measurement process. It is animated and zooms into the most important things for each step. You can save the measurements of a machine for As found and As left in the same file.

Vertical/flange-mounted machines

For measurement and alignment of vertically and flange-mounted machines.

Soft foot check

Alignment work begins with a soft foot check. The soft foot check ensures that the machine is resting evenly on all its feet by indicating which foot/feet should be adjusted. This is an important part of securing a reliable alignment. After the soft foot check is complete, you can go directly to the alignment program with all of the machine’s distance values saved.

Values – digital dial indicators

The Values program has a clear digital representation of the laser target, and a list view for recorded values. Use it to measure as with dial gauges and to check bearing play.

Belt alignment*

Using the system you can align sheaves and pulleys with digital precision. Adjustment of the machines is displayed in real-time on the screen, with readings for angle and axial displacement in both the vertical and horizontal axes, as well as an adjustment value for the front or rear foot pair. The result can be documented as normal. (Requires the XT190 BTA accessory.) 

Vibration analysis*

Diagnose vibration level, unbalance, misalignment, and looseness. (Requires the XT280 accessory.) 

Measurement methods


Measurement points are recorded at fixed points 9, 12, and 3 o’clock. This is the classic three-point method that can be used in most cases.

EasyTurn™ function

The EasyTurn™ function allows you to begin the measurement process from anywhere on the turn. You can turn the shaft to any three positions with as little as 20° between each position to register the measurement values. Voila! Measurement is complete!
