Is your machines aligned?

Some studies over the past ten years indicate that 50% - 70% of all premature machine breakdowns are attributable to poor alignment. Furthermore, some surveys indicate that up to 90% of all machines run outside their recommended tolerances. Therefore, misalignment is widely recognized as the single largest source of excessive machinery vibration, and the associated premature failure that accompanies it.

Alignment related problems are such as pipe strain, soft foot, improper base-bolt torque, incorrect thermal growth specifications and an inadequate machine base may all produce poor alignment when even when measurements suggest otherwise.

Precision laser alignment has proven capable to improve machinery service life via extending Mean-Time-Between-Failure, increase bearing life, increase seal life, reduce overall vibration level and reduce energy consumption.

What is alignment?

Alignment is the process to ensure both the drive and driven shafts or pulleys are having the same centerline or lined up perfectly on both horizontal and vertical direction.

Types of Misalignment

There are two types of misalignment: parallel and angular misalignment. With parallel misalignment, the center lines of both shafts are parallel but they are offset. With angular misalignment, the shafts are at an angle to each other. Errors of alignment can be caused by parallel misalignment, angular misalignment or a combination of the two.

Benefits of alignment

• Prevent recurring machine failure due to alignment

• Reduce friction and energy consumption

• Extend bearing, seal and coupling service life

• Reduce overall vibration and noise

• Reduce overall maintenance costs

• Increase machine uptime and product quality

• Safely extend the life of equipment

Method of alignment

There are two types of Laser systems commonly used today, based on different techniques:

• The single Laser, with a single target.
• The twin Laser, using the reverse indicator technique.

The illustration shows a typical twin laser alignment kit set up, ready for use.

Cost Savings on Laser Alignment

The most common method of a straight line, thickness gauge and your eyes is compared to the "Laser Method." With the eyeball method, as the illustration shows, you measure the alignment of the shaft. Using Laser Shaft Alignment method you have much more accuracy and precision that greatly improves the results from proper alignment.

The bottom line is Laser Alignment equipment and services will pay for itself in only a few months.
