to use by a technician with minimal training and experience.
When to use:
• For most machines with few variables: motors, pumps,
fans, compressors, blowers, belts and gears
• For diagnosing common machine faults (90 percent):
imbalance, misalignment and bearings looseness
• For technicians who have many tasks to get done (no
time to analyze complex graphs)
Fixing Shaft Misalignment With An Advance
Laser Alignment Tool
Vibration testing often reveals shaft alignment issues.
However, fixing that misalignment is another issue that
can require specialized equipment. Shaft misalignment can
cost the average facility thousands of dollars per year in
replacement bearing cots, unnecessary repairs and crippling
Traditional methods of shaft alignment include a straightedge or feeler gauge, which only has the resolution of the
human eye. Precision laser measurements use advanced
technology to reduce errors and provide increased accuracy
and more repeatable result than other methods. The computer handles the calculations and walks you through a guided
A laser shaft alignment system reduces the potential for
human error and can have resolutions as good as 1/1000 mm
or 1 micron (0.00004 in).
Benefits of laser shaft alignment:
• Less energy consumption with increased efficiency
• Fewer unexpected or catastrophic failures
• Reduce mechanical seal repairs
• Reduce pump repairs
• Reduce cost of spare parts
• No shaft cracking or failures
• No loose foundation bolts
• Extend machine life
The best laser shaft alignment tools are easy to use with
minimal training and include an “all-in-one” result screen
shows both coupling results and feet corrections (vertical
and horizontal) and also provide immediate and dynamic
feedback of the alignment status while you are adjusting
the feet. They also perform final alignment checks and print
reports with ‘as found’ and ‘as left’ measurement results to
document the procedure.
After decades of either primitive or extremely unwieldy
and expensive vibration analysis, recent developments in the
field have enabled a broader application of the practice. Now
a critical component of condition-based monitoring programs, vibration analysis continues to evolve, with tools that
diagnose and help fix problems more easily accessible and
affordable to the average user.
