LASER ALIGNMENT
Northwest Industrial Repair offers a laser alignment service using
ROTALIGN. By using a laser alignment tool
problem analysis is simplified and alignment is done in a fraction of the time that it would take using older methods.
Our experienced technicians have aligned machinery ranging from 50HP to 500HP motors and pump combinations.
LASER ALIGNMENT BENEFITS
Reduces bearing vibration, stress and extends bearing life.
Reduces motor amps and can result in significant electricity savings.
Minimizes coupling wear.

ALIGNMENT METHODS.
STRAIGHT EDGE
The straightedge is the most well-known and widespread shaft
alignment tool. If both the coupling surface and the measuring eye are in good condition, alignment accuracy
may approach 1/10mm (5mils). This may be sufficient for some machines and couplings. Thanks to its simplicity,
the straightedge is ideal for quickly performing a rough preliminary alignment.
DIAL INDICATORS
Dial indicators offer much more accurate alignment readings: when used correctly, they can achieve shaft alignment
accuracy of 1/100mm (.5mils). To do so, however, bracket sag must always be measured first, and the mounting
arrangement must be very rigid. The measurement values must be recorded correctly (without mixing up +/- signs
or transponding values, of course) and then the alignment must be correctly calculated from the indicator readings.
LASER OPTICS
This approach has the highest accuracy available.
ROTALIGN has an actual resolution
of 1/1000mm- better than any other available system. Laser optics also gives the user several other distinct advantages.
Custom-made brackets are no longer required for each individual machine/coupling arrangement. Instead, since no
mechanical linkage across the coupling is involved, just a few universal brackets can be used to mount quickly
on nearly every machine. Measurements must no longer be read and written down, and correction values for the
machine feet appear automatically in the display.
