Simple and efficient shaft alignment

Easy-Laser® E540 is a very powerful shaft alignment system, with the ideal balance between performance and price. Program that guides step-by-step with both icons and text makes the system very easy to use for everyone, regardless of prior knowledge.

The E540 system includes measurement programs for horizontal machines, vertical machines and alignment of machine trains with three machines. The measuring units are pre-mounted for rapid machine set-up. Start with the measuring units positioned anywhere through 360 ° around the shaft, then take any three readings down to 20° in-between. Then adjust the machine with the live-values in both horizontal and vertical directions. A PDF report is generated automatically when the measurements are saved. Simple and efficient! 

Technology that gives the best performance in demanding industrial environments

The shaft alignment system has a large 5.7", bright colour display that clearly shows all the steps of the measurement. The measuring units have TruePSD-technology, which gives unlimited resolution. Twin laser beams, twin PSDs and twin inclinometers give you superb control of the measurement in all situations. The measuring units are incredibly compact featuring wireless technology, an integrated rechargeable battery and large 30 mm TruePSD detectors. This means that they are easy to install on most types of machines, even where there is limited space. The wireless technology gives you full freedom of movement around the machine that is to be aligned. Display unit, measuring units and fixtures are all very robust for the highest accuracy in demanding industrial environments. 

Large expansion possibilities

Using XT190 BTA you can check and align sheaves and pulleys with digital precision. You can document the measurements for belt alignment in the same way as for the normal shaft alignment programs. There is also a wide range of accessory brackets, such as magnet bases, axial magnet brackets and brackets for non-rotating shafts. The transportation case is equipped with recessed compartments for the accessories, which means that you can carry everything in one case. 

  • Compact, wireless measuring units for use on most machine designs.
  • Integrated wireless units and rechargeable battery
  • TruePSD technology with unlimited resolution.
  • Dual PSD, dual laser beams and dual inclinometers for superior control and accuracy.
  • Produce PDF reports directly from the display unit and save to USB memory.
  • IP65-rated design that withstands harsh environments
  • Expandable / Adaptable. A range of accessories means that you can adapt the measurement system to your needs.

The key to a quick and reliable measurement are programs that guide you through the measurement process. The Easy-Laser® systems support you with smart functions and a clear user interface. Still, it is not our products that do the job, but you as a professional technician!


Horizontally mounted machines often consist of a pump and a motor, but can also include other types of machines such as gearboxes and compressors. Regardless of the machine type, it is easy to measure and align with Easy-Laser®. The measuring units (M and S) are easily mounted on each side of the coupling and communicate with the display unit wireless. Then follow the step-by-step instructions on screen.


This program is used for alignment of vertical and flange-mounted machines, e.g. pumps, motors, gear boxes. Shows centre offset, angular error and shim value at each bolt.


For alignment of machine trains with three machines. You can pick the reference machine manually, or let the program choose one that will minimize the need for adjustments. 


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 or shaft load. Can also be used to perform many types of geometric measurements.


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.)


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.


This function allows you to adjust machines in real time with the measuring units positioned anywhere on the shaft. It is ideal for situations in which outside objects interfere with normal positioning.


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!


Oftentimes, machines expand considerably when moving from a cold to hot operating temperature. The Thermal Growth Compensation function allows the measurement system to calculate the appropriate shims and values needed to make adjustments in such cases. Compensation values for the machines are normally supplied by the manufacturers.


Measurement results can be checked against pre-defined tolerance tables or values you determine yourself. This allows you to immediately see if the alignment is within the approved parameters, thereby considerably reducing the amount of time spent on alignment.


This function allows you to lock any pair of feet on the machine, giving you more freedom when aligning,base-bound or bolt-bound machines.


An advanced electronic filter function can be used to achieve reliable results even under poor measuring conditions. Air turbulence and vibrations from adjacent machines are no match for the Easy-Laser® filter function!


The software can adjust to machine designs of all types such as those with two pairs of feet, three pairs of feet, and feet in front of the coupling, etc.


The swap view function allows you to adjust the position of the motor on screen to correspond with the position of the machine in front of you, making it easier to understand adjustment directions.


All our measurement systems come with the extremely useful Values program. The program can be used e.g. when one wants to measure as with dial gauges and to check bearing play. With the standard equipment and completely normal set up on the machine!

Document your data

Connect to you computer

The display unit is connected to the computer via the USB port. It then appears on the desktop as a USB Mass Storage Device from which you can easily transfer files.


With the EasyLink™ database program you can save and organise all your measurements in one place, produce reports with both data and images and export to your maintenance systems. You can customise what your Excel reports should look like and what data should be visible and where it should be positioned. The program has a clear folder structure, where you drag and drop files from the display unit to the database. Create your own structure with folders for manufacturer, department or machine type for example. The database can also be located on a common server and shared with other users. For extra safety you can use EasyLink™ to make backups of what you have saved in the display unit.


Quickly print all measurement data locally with a thermal printer (accessory).


The barcode reader is used to enter the measurement object data automatically before measurement, which can save you time, and minimizes errors. Barcode reader is an accessory.


When measurement is complete it is possible to generate a PDF report containing graphs and measurement data directly in the measurement system’s display unit. All the information about the measurement object is documented, and you can add your company’s logo and address details if you so wish.


Save all measurements in the display unit’s internal memory. 


Save desired measurements on your USB memory. This enables you to take it to your computer to print reports whilst leaving the measurement system in place.
