Easy-Laser® XT660 - Shaft alignment

More possibilities with dot laser

Easy-Laser® XT660 Shaft is an advanced measurement system for alignment of horizontal and vertical/flange mounted rotating machinery. With XT660 you can carry out the following:

  • Align the machine
  • ​Check base twist
  • Check bearing play
  • Check soft foot
  • Document and share the results

The XT660 measuring units utilize dot laser technology. This makes it possible to measure larger machines and longer spans than line laser systems. It also provides higher accuracy when backlash in the coupling is present. In addition, dot laser allows you to check more things when installing a machine, e.g. twist of foundation and bearing clearance.

With the XT660 you have a choice of several different measurement methods, e.g. continuous sweep and multipoint. This gives you the flexibility you need to achieve the perfect measurement result.

The XT products are rugged, rated both IP66 and IP67 water and dust proof. Along with long operating times, this guarantees you will be able to take on and finish even the tougher jobs.

User-friendly

Use the rugged Easy-Laser XT display unit, or install the free XT Alignment app on your iOS or Android device. The intuitive user interface guides you through the measurement process. Click here for list of compatible devices

Unique documentation possibilities 

The XT display unit has a 13MP camera. You can also get the XT display unit with a built-in IR camera. This means you can add a thermal image of the machine before and after alignment. You can easily create and share a PDF report containing all measurement data and images.

Blog:Shaft alignment with 5 different measurement methods

The Generation XT shaft alignment systems give you access to five different measurement methods. Each with its own advantages. Read more to find out how to use them best! Read more

Measurement programs

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

Horizontal machines

The user interface is intuitive and guide 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.

Easy-Laser XT machine train
Machine train (3 machines)

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. 

Alignment program for cardan/offset mounted machines
Cardan/offset mounted machines*

For alignment of cardan/offset mounted machinery. (Requires additional Cardan bracket kit.)

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.

Twist measurement

Program to measure flatness/twist of, for example, machine foundation, machine tables, etc. 

Values – Shaft alignment applications

Use the M and S measuring units included to measure as with digital dial gauges, but with laser precision and the possibility to document the measurement result. Another application is to check shaft radial play (bearing play).

Belt alignment program
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

9-12-3
9-12-3

Measurement points are recorded at fixed points 9, 12 and 3 o’clock. This is the classic three-point method which can be used in most cases. The preferred method for situations where the machine to be aligned is mounted on a moving object, and it is not possible to use the inclinometers (e.g., on ships, cranes, wind turbines etc.).

EasyTurn™ function
EasyTurn™ function

Ideal method for coupled machines where you manually rotate the shafts to any position. 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. An easier-to-use version of the three-point method (see 9–12–3). 

Multi point
Multi point

Multi point is basically the same as EasyTurn™, but instead you can record multiple points on the sector rotated. This will provide an optimized calculation basis. Perfect for e.g. turbine and sliding bearing applications. 

Continuous sweep
Continuous sweep

Automatic recording of measurement values during continuous sweeping of the shaft. The easiest and quickest way to obtain the alignment status on coupled machines. Hundreds of points are registered. Start recording, rotate, and stop at any angle and you get the results instantly. Quality check of measurement is provided (see example down left).

Uncoupled sweep
Uncoupled sweep
Uncoupled sweep

Used when the machines are uncoupled and when the rotation can be difficult to control. Rotate one shaft/unit at a time to pass with the beam over the other (stationary). Repeat alternately until enough measurement points are recorded. You can start and stop anywhere on the turn. Use it for big heavy machinery like gas turbines, wind turbines or gear boxes which can be difficult to rotate to a specific position.
