SHAFT ALIGNMENT Quick, simple and effective.


Easy-Laser® D450 is a basic system, with the performance and potential for expansion of our more advanced ones, for example D505 and D525. In fact, with the right accessories your D450 system can be converted into any other Easy-Laser® system!

The general idea behind the system is “simplicity for the user”. All parts included in the system are developed for rough use and to be easy to mount on the machines. As a user you are given step-by-step instructions on the display through the entire measurement procedure. Even though the technology inside is rather advanced, the measurement principle is straightforward. It is based on the “reverse indicator method” with two laser/measuring units mounted on each side of the coupling.

System D450 includes two measurement programs: Horizontal shaft alignment and

Softfoot*. The displayed measurement resolution can be set as low as 0.05 mils/thou [0.001 m]. When the measurement is complete you can produce a printout, save in the display unit or transfer the data to your PC.

*The display unit can be expanded with other Easy-Laser® measurement programs. Please see last page.

With this program you can easily check that the machine is standing evenly on all feet. This is a necessary condition for reliable alignment. Following the softfoot check, continue directly to the alignment program, with all machine parameters already entered.

4. Offset, Angular values and Shim and Adjustment values are clearly displayed. Both horizontal and vertical values are shown “live”, which makes it easy to adjust the machine.

2. Enter the distances between the measuring units and feet. (If not already entered when performing Softfoot check.)

Press the Enter buttonat each

position to record the value.

The measurement is ready!

A.Offset value. B.Angular value. C.Shim/Adjustment values. Live direction indicated by filled machine feet symbols. D.Tolerance settings display. Select speed range. E.E.E.E.E.Filled coupling symbols, indicating that alignment is within tolerance.


Shim this foot before alignment

HORIZONTAL 9–12–3 - For alignment of horizontal machines by the 9–12–3 method.

SOFTFOOT - With this program you can easily check that the machine is standing evenly on its feet. Shows which foot should be corrected.

THERMAL GROWTH COMPENSATION - Compensates for difference in thermal growth between the machines. Sub function.

TOLERANCE CHECK - Checks the offset and angle values in relation to selected tolerance. Shows graphically when the alignment is within tolerance. Sub function.

MEASUREMENT VALUE FILTER - Advanced electronic filter function for accurate measurement result even in poor measuring conditions like air turbulence and vibration. Sub function.

When measurement is complete, you have several options for documenting the results. Choose the one that is best suited for the situation, depending, for example, on whether further analysis is needed or whether a measurement report needs to be produced. A keyboard with all characters available makes it quick and easy to give each measurement a unique description.

SAVE IN THE DISPLAY UNIT You give every measurement an individual name. The system then adds the time and date of the measurement. Up to 1000 shaft alignment measurements can be saved.

PRINT Quickly print all measurement data locally. This is useful, for example, if you don’t want to connect the display unit to a PC.

With the EasyLink™ program for Windows® (included), you can produce professional reports with both measurement data and pictures, export to spreadsheets such as Excel®, etc.
