  • Pipe Strain Was the Issue

    Have you ever struggled with a precision shaft alignment, even though you did everything right? (Preformed the pre-alignment steps, controlled backlash, etc., etc.) So, what was different? Maybe it was pipe strain.

  • Fixturlaser Runout Probe

    The Fixturlaser Runout Probe, an accessory for the Fixturlaser NXA Pro and Fixturlaser NXA Ultimate, is an electronic tool designed to detect and measure shaft runout and pipe strain. Runout and pipe strain are often overlooked, but when present they can confound the measurement and correction of shaft alignment.

  • Precision Alignment and Balance isn’t Important – Unless you care about budgets and the reliability of your rotating assets.

    I read an interesting article in the June/July 17 issue of Uptime Magazine. It was titled “The Reliability Impact Within the P-F Curve” by Randy Riddell. Randy is the Reliability Manager for the SCA Barton Mill in Alabama.
    I encourage you to read the full article (https://reliabilityweb.com/articles/entry/the-reliability-impact-within-the-p-f-curve). The article includes the following graphic t

  • What is Extended Alignment function?

    If possible we want to have the sensors in a horizontal plane when the live screen is activated so the sensors are in position to monitor the horizontal correction. For rotating machines with large mass or that are difficult to position precisely, this may be time consuming and/or not possible.

  • The Cure for Alignment Frustration!

    A customer called me, extremely frustrated, because he could not get a good alignment. “I’ve spent two hours trying to align this stupid pump!” he said. He blamed the laser, the “cheap” pump his company had, the bad base, his bad trainer (me), and anything else that came to mind.
    I did not take it personally, because I’ve been there too! I listened to his frustrations, and let him vent. And

  • Roughing In Before Precision Shaft Alignment

    Some people believe that precision laser shaft alignment has evolved to the point where pre-alignment steps, such as roughing in the alignment with a straightedge, are no longer needed. Well, quite frankly, those people are wrong!
    The reason for roughing in the alignment has little to do with how accurately the lasers/sensors measure. It has nothing to do with how big the laser detector is, o

  • When Should You Replace the Coupling Insert?

    In industry, many couplings utilize an elastomeric insert or element. This type of coupling has many advantages, among them: Ease of replacement Ability to absorb torsional loading No need for lubrication Tolerant of slight amounts of misalignment Inexpensive

  • The Tripoint method!

    The Tripoint method of laser shaft alignment allows the user to manually take the measurements at 3 points while rotating the shafts at least 60 degrees.

  • Save Time. Save Money.

    I had the pleasure of working with the maintenance team at a South Carolina manufacturing plant that had an outstanding alignment kit they rolled out to every alignment job.

  • Clean Your Rotating Machinery

    Keeping equipment clean and tidy is not always the easiest thing to do when maintenance and operations has full duty schedule.

  • When an Alignment Check Turns into Starting from the Beginning.

    A recent Fixturlaser NXA Pro training class performed an alignment check of a winch driven by an 80 HP, 1800 RPM, DC electric motor with a gear style coupling. The initial results revealed a misaligned machine, with a vertical angularity over 13 times the tolerance of 0.7mils/1” (1.0 mil = .001”), vertical offset six times tolerance of 4.0 mils. The horizontal angularity was almost 4 times to

  • Why and How to Measure in Clock Method!

    By Tom Shelton, Vibralign
    Proper use of any tool is essential to success in achieving your desired goal. Many tools have optional configurations to adapt that tool to your needs. Fixturlaser Precision Alignment Systems are no different. The alignment tools produced by Acoem/Fixturlaser are second to none in ease of use. The Acoem AB design engineers do all they can to provide the end user with

  • It’s All About The Base

    By Mac MacCormack , Vibralign
    From the editor –  Trainers see many different machinery base designs and installations during the OJT portion of our training classes. Some bases are quite substantial while others are flimsy and actually downright horrible Poor bases have a negative impact on rotating machinery reliability and can certainly be a cause of precision shaft alignment frustration.

  • OL2R – The True Measure of a Machine’s Movement!

    OL2R is the acronym for OffLine 2 Running. OL2R is an optional program and special precision bracket set that is available for the Fixturlaser NXA Pro & Ultimate. This option allows the shaft aligner to accurately measure vertical AND horizontal changes of machines from a static (OffLine) position to a Running position.
    This allows for very precise targeting of rotating machinery durin
