It’s The Little Things

By on April 20, 2017

When we trainers conduct training, the first thing we want to know is what is your cause of frustration or “pain” when performing a precision shaft alignment. What we consistently hear is repeatability as the foremost cause of frustration. First the laser says add shims, then take them out, then add and so on. In […]

Clean Your Rotating Machinery

| |

By on April 13, 2017

Everyone knows that keeping rotating equipment clean and free of debris and dirt will prolong the operational life allowing for maximum efficiency and performance.  Bearings, seals and other components will last longer and perform better plus repairs and alignments will be faster and easier. Motors, pumps and machinery with excessive dirt build-up will fail more often […]

Is there such a thing as “Too Good” of a Precision Shaft Alignment?

| |

By on April 6, 2017

This question comes up frequently in our Shaft Alignment Best Practices training classes. The result screens below both show two different aligned machines meeting 3600 tolerances.   The question is; is one better than the other? There has been a lot of discussion about this very topic. The theories are abundant and points of view […]

When Should You Replace the Coupling Insert?

| | | |

By on March 30, 2017

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 It is important to remember that even though these elastomer couplings can be tolerant of misalignment, the […]

When an Alignment Check Turns into Starting from the Beginning.

By on March 22, 2017

A recent 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 […]

Maintenance Strategies: Part Four – Proactive Maintenance

| | | | |

By on March 16, 2017

Proactive Maintenance includes a number of maintenance strategies, such as Precision Maintenance, Reliability Based Maintenance, Reliability Centered Maintenance, and Root Cause Failure Analysis. The idea is to anticipate and solve problems before they become problems. Reliability Centered maintenance would begin with a study done on a piece of equipment to gain understanding of all its […]

Maintenance Strategies, Part Three – Predictive Maintenance

| | | |

By on February 21, 2017

Predictive Maintenance, also known as Condition Based Maintenance or affectionately known as “if it ain’t broke, don’t fix it” also has its own set of pro’s and con’s. The pro’s: Rotating equipment usually gives warning signs before failure. Vibration level or pattern changes, rise in temperature, wear detected via oil analysis, performance change, motor current […]

Positive/Negative

| | | | |

By on February 7, 2017

When we align equipment, we are aligning the rotational centerlines of the shafts. We have a stationary machine and a moveable machine. In most cases the stationary machine’s center of rotation is the target and reference for all measurements and corrections of the movable machine. When reading laser or dial indicator values, the terms of […]

Maintenance Strategies: Part Two

| | | |

By on February 1, 2017

Preventive Maintenance, also known as planned maintenance, scheduled maintenance, calendar based maintenance, historical maintenance, etc. has its own set of pro’s and con’s. The theory is machinery has a life cycle. The probability of failure increases as the machine ages so maintenance needs to be performed prior to failure to extend its life and avoid […]

The NXA Extended Alignment Function – What is it? When to use it.

| | | |

By on January 25, 2017

When training clients to use VibrAlign’s Verti-Zontal Alignment Process we show taking the 3rd measurement at a horizontal position, typically at 3 o’clock. This is simply for expediency and is NOT a requirement as Fixturlaser Shaft Alignment Systems can take measurements at any position due to the inclinometers in M & S sensors. If possible […]

The One Tool Missing in Most Aligner’s Toolboxes

By on January 18, 2017

I am going to pass along to you a gift – one that I believe could potentially cut your alignment times-maybe by more than half!  One that could lessen loosening and tightening bolts, reduce frustration, and increase your “alignment” confidence substantially!  Would you like such a gift? Well, here it is – measure your shim […]

Are Flexible Couplings Designed to be Misaligned?

| | | |

By on January 12, 2017

A common misbelief that occasionally comes up in our precision shaft alignment training classes is that, elastomer insert flexible couplings are designed to allow misalignment between rotating machinery shafts.  This is not the case.  Although this type of coupling may be more forgiving to the effects of misalignment, they are definitely not intended to be […]
