LASER ALIGNMENT

Shaft alignment, often called “coupling alignment”, is a process to make two or more rotating shafts co-linear, or in the same straight line, both vertically and horizontally. Shaft alignment can be done utilizing several methods and tools, such as straightedges, calipers, dial indicators, optics, or laser systems. Of these, laser shaft alignment is the fastest and most accurate.

​

Laser tools are rotated to various positions around the rotational centers of shafts. This process allows the laser to measure just the rotational centers, and is not affected by shaft or coupling eccentricity, or runout.
