Alignment & Balancing
"In my 40 years of experience, I’ve seen countless reliability programs chase complex solutions to complex problems while ignoring the fundamentals. What I’ve learned is this: your machines aren’t that complicated.
If they could talk, they’d tell you, “Friction, Lubrication, Alignment, and Balance—fix these first!”
...it’s where every asset reliability journey should begin"
Ian Ware

Alignment & Balancing instruments may look similar, but there is a difference!
Acoem was a pioneer in the development of the world’s first shaft alignment tool with visible red laser and integrated software that calculated measurement values, the use of touchscreens with icons and graphics for industrial instruments in the mid-1990s and introduced wireless sensors in the mid-2000s. Trusted for over 40 years, they continue to lead the industry today.
The Path to Alignment Success
Shaft alignment is a cornerstone of reliable machinery operation and crucial to protecting the operational efficiency and life expectancy of your rotating machinery.
It also reduces stress on your equipment and helps avoid unexpected failures which may cause full process shutdowns or safety incidents.
Motors face three main types of misalignments: angular misalignment, offset/parallel misalignment, and combination misalignment—when a motor shaft experiences both types of misalignment at the same time.
In the case of pumps, misalignment causes higher energy consumption and their parts experience greater wear and tear, which means more frequent maintenance and higher cost. Bearings, seals, and shafts all wear down more quickly when your motors and pumps are misaligned.
Misalignment also causes excessive vibration, which if left unchecked, can go on to damage other components, leading to extended downtime.
Even the smallest angle misalignment can reduce the lifespan of your components by 50% with studies revealing that large industrial and manufacturing facilities lose (on average) 323 production hours annually due to unplanned downtime and a major contributor cited was improper machinery alignment.
Fixing shaft alignment issues is one of the simplest ways to extend the life of your equipment and save your business both time and money.
With Acoem task-oriented laser shaft alignment tools, you can be confident that your machinery will be aligned quickly, easily and accurately every time, with all the guidance you need available via your tablet or smartphone.

Four decades of excellence in alignment
What began as a mechanical workshop in Sweden in 1984, evolved to become an international leader in laser-based shaft alignment for rotating assets. Acoem developed the world’s first shaft alignment tool with integrated software that calculated measurement values with visible red laser and additional functionality, such as measurement of straightness, perpendicularity and parallelism.
​
We were pioneers in the use of touchscreens with icons and graphics for industrial instruments in the mid-1990s and introduced wireless sensors in the mid-2000s. We have continued to design and manufacture cutting-edge, user-centric alignment solutions that require minimal set-up time and utilise application software that empowers mechanics and maintenance teams. We remain committed to focusing on digitalisation, ease of use and accessibility for our customers worldwide.
