Modern Laser Alignment Systems make shaft alignment faster, easier and with much greater accuracy than older dial indicator alignment systems. Using Laser measurement tools instead of Dial Indicators offers  additional advantages as it eliminates sag and thermal changes in the dial indicator rods or bars. A Laser Shaft Alignment System does all the calculations and graphically prompts you through each step of the alignment process. Reliability Direct, Inc. offers field proven laser alignment tools from multiple manufactures including Damalini/EasyLaser, SKF and VibrAlign for both horizontal shaft alignment and vertical shaft alignment applications.
