Laser Alignment

RayLin Engineering provides various calibration and laser alignment services. Of note we specialise in shaft alignment, or “coupling alignment”. This involves 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, RayLin Engineering has opted to use laser shaft alignment is the fastest and most accurate.

Laser shaft alignment systems offer numerous advantages:

  • Laser beams are not affected by gravity or bracket sag.
  • 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.
  • Most laser shaft alignment systems have on board software to calculate extremely accurate values for shimming and horizontal corrections.
  • Some laser shaft alignment systems use “live” measuring modes to monitor the actual shaft rotational centers during the movement process taking into account both intended and unintended movements, allowing the aligner to monitor total movement, and know when to stop.
  • Many also allow storing the corrected alignment values digitally, for later integration into maintenance record keeping.
  • Some laser shaft alignment systems also have programs to measure and correct soft foot, bolt bound or base bound conditions, and other shaft alignment problems.
  • Accurately measure more complex alignment functions such as cardan shaft, or universal joint parallel alignment.
  • Laser shaft alignment systems can also measure long-span alignments in situations where spacer shafts are used, such as in cooling towers and paper machine applications.
  • These laser shaft alignment tools are considered “state of the art” in most industrial and maintenance applications.
