Hot alignment checks are often unsuccessful because of delays in installing measuring devices on the equipment which has just been shut down. Even when good planning and organization allowed you to take readings within minutes of shutdown, these readings only address the so called “Thermal Growth”. Often the effects of thermal growth on alignment had [...]

The biggest contribution one can make to lower the operating costs of rotating systems is to align them correctly using the real coupling target values. Target values recommended by manufacturers do not always reflect the real machine centerline movements due to thermal growth, pipe strain and dynamic factors. The new ROTALIGN ULTRA Live Trend, a [...]

Ludeca, Inc. presents “Laser Align“, a free reference tool for shaft alignment of rotating equipment. With this app, you can access important reference material and learn about key laser shaft alignment concepts. “Laser Align” features the demanding tolerances that have been the industry norm, pioneered by Ludeca in 1983.  These exact same tolerances are used [...]

We’re proud to announce to all current Rotalign ULTRA (ALI 4.202 alignment computer) that you can now upgrade to our latest shaft alignment firmware release! Here is a glimpse into what this update has to offer: Soft foot interface is even easier and machine coupling is now displayed. Soft foot tolerance can now be set by the user for each machine. [...]
