We are pleased to announce the launch of our new improved GuideU™ (UI), designed to maximize user productivity, facilitate intuitive reporting, and ensure a consistent user experience across all measurements.
These are the five questions every maintenance supervisor needs to answer.
There are many tools on the market to use in conjunction with lubrication – mechanic’s stethoscopes, “smart” grease guns which use ultrasonic, or just an ultrasonic tool itself. High-frequency vibration measurements can also do this.
When using a straightedge to perform a shaft alignment you won’t see angular misalignment.
We have several times discussed the differences between coupling alignment tolerances and precision shaft alignment tolerances. As stated in those text the coupling manufacture’s tolerances are for the coupling. As maintenance professionals we are concerned with the coupling, however we are more concerned with the bearings in the machines.
A key thing to understand when it comes to belts is proper sizing. Whether you are using a correctly-sized belt for your machine will have a significant impact on the machine’s ability to function at an optimal level.
We’ve identified 6 common machine faults you’ll likely encounter on your maintenance routes.
During a recent class in a shipyard, there was a need to perform a Cardan Shaft Alignment in a boat with very little space to work in. It also required shooting the lasers through a hole in a bulkhead.
Looking from the S sensor through the bulkhead at the M Sensor mounted on engine output shaft

It was a challenge, but the guys rose to it
Using Your Laser Alignment Tool to Measure Pipe Strain Induced from Tightening Flanges
The FIXTURLASER Laser Kit consists of two wireless sensor units utilizing two line lasers. The use of line lasers simplifies the setup process minimizing setup time. To make it even easier, the sensors comes pre-mounted on its fixtures and pre-set to the most common setup.
The augmented mechanic’s solution – RT-300 – is a smart reliability tool that combines on-the-spot machine diagnostics with tools for pre-alignment and precision shaft alignment, minimizing the time from fault diagnostics to corrective actions.
Precision shaft alignment of wind turbine generators mounted on adjustable chocks is as straightforward as when aligning rotating machinery mounted on chocks down at ground level.
In the case of a recent NXA Training Class in a Vestas V82 we knew before going up-tower that one revolution of the adjustable chocks equals 1mm. Also, as there are 6 holes in the chocks, we calculated that the hole t
Vibration analysis is a useful way to monitor machine health. Many plants have implemented regular vibration analysis plans to ensure the condition of their machines is being checked at regular intervals and so, if an issue comes to light after spectral analysis, a solution can be pursued.
When analyzing vibration, it is important to be familiar with several terms. These are:
Frequency
Disp
When performing vibration analysis, it is observed that machines with VFD drives have a more frequent occurrence for changing motor bearings. If you’ve been diligent in the installation and maintenance of these machines, ensuring the alignment and balance are within specification and the bearings are properly lubricated, but still have frequent bearing failures, it may be your VFD drive.
I
For the field portion of a recent training class, the decision was made to check the alignment on a plastic extruder. At first glance, checking the alignment of the motor shaft to gearbox input shaft is pretty straightforward. However, the output side of the gearbox had two shafts, so maybe this is not so straightforward. And to complicate things a little more, there are three more chambers co
We want to offer some helpful maintenance tips from our trainers in a single blog post. This blog is a collection of useful troubleshooting tips, maintenance reminders, and pieces of advice from people who have been in the maintenance industry for many years and have seen a thing or two and want to pass their knowledge on to you!
We have categorized the tips below so that you can focus on the
Fixturlaser LEVEL is used for levelling machines or machine parts during installation and gives accurate measurement results. The measuring sensor measures the angular deviations from the surface in two axes using a wide measurement range (± 50 mm/m), high accuracy and with a resolution down to 0.01 mm/m.
When performing the Ariel ER-82 Top Plane Compressor Frame Measurement, surrounding reciprocating compressors in operation may cause repeatability issues due to excessive vibration.
Establishing good habits with sensor placement will get you one step closer to determining the health of any machine.
Recently, we was called to consult with a customer to recommend a procedure and alignment tools for a very long-distance vertical pump alignment. First, we will describe the machine and then how we aligned it. This large raw sewage pump machine train begins at the driver level. In this plant, floor levels are described by relationship to sea level. At the top level (+35), the primary mover, a
