A customer called me recently with concerns about a pump alignment job he completed about six months earlier. He had checked the alignment again and found that the alignment values changed. He was concerned that he had done something wrong. I explained to him that he was performing the alignment correctly, however, the machine could have moved. How? He asked. Good question!
RT-300 Solution's laser alignment, vibration analysis & Run Out Probe helped align Caterpillar engine to backup floodwater pump.
Har du någonsin lagt till antalet shims som ditt uppriktningsverktyg säger att du ska göra bara för att upptäcka att din maskin fortfarande inte är korrekt? Detta är en frustrerande men vanlig förekomst. Var det ett beräkningsfel eller gav ditt axeluppriktningsverktyg dig fel information? Mer än troligt är dina shims är skyldiga.
Tolerances for shaft alignment are typically expressed in terms of angle and offset. It is common knowledge that offsets cause confusion, but angularity often confuses those tasked with aligning or verifying alignments.
There are two parts that must be understood, proper phasing and angularity of the input and output shafts.
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.

To calculate the cost of misalignment, first determine the cost of the machine’s downtime.
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.
The NXA Runout Probe is a simple electronic tool designed to detect and measure shaft runout. The new tool represents a unique application of a linear variable displacement transducer (LVDT) to provide an easy-to-use but highly accurate measure of machinery problems that can confound the measurement and correction of shaft misalignment
Predictive maintenance involves scheduled testing on regular intervals.
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.

It was a challenge, but the guys rose to it
​A lift check isn’t always done when performing a precision shaft alignment, nonetheless excessive lift can be the cause of alignment frustration.

The NXA Runout Probe was introduced as an accessory to the NXA Pro and Ultimate alignment tools. As originally envisioned, the runout probe was designed with shaft and coupling runout measurements, and direct soft foot measurements in mind.
