The Cure for Alignment Frustration!
When laser alignment tools are not repeatable, it’s not the laser – IT’S YOU.

Don’t Overlook “Hidden Shims” Under the Feet!
The initial set of alignment results indicated horrible angular misalignment (14 to 16 times tolerance) and offset misalignment (6 to 8 times tolerance) in the vertical and horizontal planes

THE GOAL of a precision alignment is to align the machine within tolerance!
Thermal growth is not rocket science. However, it is often misunderstood. We see people causing harm by compensating for thermal growth incorrectly.

Dial Indicator Alignment – Bar Sag Still Exists in 2018!
Dial indicator bar sag describes a bending of the hardware used to support a dial indicator or other part which spans the coupling. The bending action occurs as a result of gravity and cannot be totally eliminated in almost all cases of alignment.

Know Your Alignment Tolerance
Fixturlaser have done what we will to form the exactness shaft alignment method faster and easier for the user of our tools. To help maintenance personnel throughout alignment a tolerance table “pops up” on the unit screen (of our tools) once getting into dimensions for the machines being aligned. The tolerances square measure supported industry standards.

Compressor Rod Runout with the NXA Runout Probe
The Runout Probe provides a digital linear displacement measurement, much like a dial indicator, but with the added benefit of electronic documentation through the Bluetooth connection with the NXA Display Unit.

Installation Errors – Hold Down & Jacking Bolts
Hold down bolts are designed to keep the machine in position after a precision alignment is performed. Jacking bolts are designed to help position a machine during the alignment. Jacking bolts are not designed nor should be used to maintain the position of a machine, that is the job of the hold down bolts. Let’s look at the design intent of each type.

Do You Have Bar Sag?
So what is bar/rod sag? Simply put, it is how much the dial indicator mounting bar deflects when the rim dial indicator is install. How much the bar/rod deflects depends upon the type of bar (solid or tube), the length of the bar and weight of the dial indicator.

What is the Difference between Unbalance and Runout?
Unbalance and runout are two terms that we hear frequently in the predictive maintenance community. Both unbalance and runout can be serious issues and need to be addressed to prevent inefficient functioning and damage to machines.
