Understanding Spacer Shaft Alignment

Blog posts   •   May 08, 2018 08:29 GMT

The spacer shaft function is used when the alignment is performed on machinery using a membrane coupling. The membrane coupling is a typical high-performance coupling, with no backlash, used for maintenance free operation. It is also suitable for high speeds or high temperature applications.

Fixturlaser SMC - is definitely a time and money saver!

Blog posts   •   May 02, 2018 10:48 GMT

Before we had the Fixturlaser SMC machine we would basically send an engineer out to site to go and investigate the pump problem, he would then return to office and write a recommendation report to the client. It use to take about two days.


Channel Strut as a Motor Sub-base?

Blog posts   •   Apr 16, 2018 11:09 GMT

At first thought it may sound like a good idea as the specialized fasteners in the channel make it easy to tighten the motor hold down bolts, however in reality it’s a cause for precision shaft alignment issues. Here’s why.


If It Moves Your Laser Will See It

Laser alignment systems are a tool and as such show the user what is occurring “mechanically” during the alignment process, including if components are moving during said shaft alignment process. “If it moves, the laser will see it”.


How to REALLY Minimize Soft Foot Every Time

Blog posts   •   Mar 05, 2018 08:03 GMT

It is both possible, and desirable, to minimize the negative effects of soft foot. While it may be difficult to completely get rid of soft foot, it can typically be reduced to a few mils, if the following techniques are used.

The Soft Foot Primer (Part 2) Vibration and Alignment Problems Related to Soft Foot

Blog posts   •   Feb 27, 2018 07:24 GMT

Most industrial maintenance mechanics who are involved with precision shaft alignment are familiar with the phenomenon of soft foot. Alignment standpoint, soft foot causes: Changes in alignment values, between when the hold down bolts are loose, and when they are tight. Non-repeatability in alignment measurements, especially if the bolts are not tightened in the same order and manner each time.

Welcome to our world of shaft alignment

Since the very beginning in 1984, ACOEM AB has helped industry throughout the world to achieve more profitable and sustainable production. We have reached where we are today by having the courage to think beyond the norm and follow slightly unconventional paths. We have had the courage to make mistakes and find new directions. Through our resolve, ambition and knowledge we have become a global player and a leader in innovative, user-friendly shaft alignment.

Sustainable innovations
During our almost 30 years in the industry, we have drafted, adjusted and experimented more than anyone. Some might say we are incurable innovators whereas others might say that we are highly focused. They probably have a point. If we hadn't been devoted and ambitious, we wouldn't have been the first in the industry to have a touch screen. Nor would we have been pioneers in the use of visible lasers and dual measuring heads.

Over the years, we have learnt to never compromise on quality and we are constantly in search of new, unexplored opportunities by combining advanced technology with design and function. By doing so, we have become the leading innovator in our sector. Not only do we minimize wear, production stoppages and costs, we also help save the environment. Natural resources are in short supply and if we can contribute to a more sustainable world by making it a little bit straighter, we couldn't be happier.
