Expensive laser alignment systems are NOT needed to obtain a precision alignment of a machine set.

Laser systems can measure very precisely, but the smallest a move a mechanic can make is 0.001" (0.025mm). They also provide a calculated solution making the alignment process quicker.

The biggest complaint from mechanics using a reverse dial indicator set is performing the graphical solution to determine the required machine moves.

Misaligned machines are responsible fro 50%-70% of machine vibration which significantly shortens machine life, increases cost of maintenance, increases of electrical cost, and lowers product quality.

RD Align is a PREMIER ALIGNMENT SYSTEM when combined with a reverse dial indicator set such as the Proaction Alignment System. For less than $1500, equal or better alignments can be achieved in the same amount of time.

RD Align will illustrate the graphical solution and calculate the required machine move. The graphical solution provides the mechanic a visualization of the machine set in the measured state.

Intuitive interface guides the user through the alignment process.
Step 1: Enter the machine set dimensions.

Step 2: Enter each machines running and stopped temperatures for thermal growth compensated alignment solutions in the vertical direction. Machine will start out misaligned and "grow" into alignment. (Optional)

Step 3: Enter vertical alignment dial positions to calculate and view the vertical alignment solution. Select 4 optional alignment solutions.

Step 4: Enter horizontal alignment dial positions to calculate and view the horizontal alignment solution. View the entire machine train to visual whole system. Select 4 optional alignment solutions.

Great Moby ,

A millwright’s dream come true!!!

Finally an excellent, well documented, easy to use and understand app to do reverse alignment. Why purchase a laser when you can use dial indicators at one tenth the cost and have this app handle the math. Thermal growth? This program handles it as well. We purchase a copy for each of our students at our hands-on training center. The author could price it at a much higher price and we’d still buy it. At $4.99 its a steal. Wait till you see it help you figure your way around a bolt bound situation in the field. Not just one solution but four. The directions for use are clear and obvious written by a guy who knows shaft alignment from a field perspective. Thomas B.Davis Mechanical Engineer. Maintenance Troubleshooting. 10/18/2017
