Choosing the Best Laser Shaft Alignment Tool

Selecting a laser alignment tool can be a challenge, as companies often face a wide range of choices. Some lean towards the most basic option, while others prefer the most advanced, without fully considering what will work best for their situation.

The most suitable tool is not defined by its position in the range but by how well it supports your goals — enhancing reliability, reducing vibration, providing clear documentation, and meeting the specific requirements of your machinery.

Before making a decision, it’s essential to have a clear understanding of your specific needs. Below is a comprehensive comparison of our AT-Series alignment tools and how they can effectively address your alignment requirements.

AT-100

An app-based solution for shaft alignment

  • 2-meter range
  • Occasional precision alignment of small machines.
  • Stock item on a typical service truck or satellite shop, especially when working remotely.
  • As a backup laser, especially for outage work or down days, when multiple alignments may occur.

Small ANSI pumps, smaller fans, light to medium commercial HVAC.

AT-200

The smart app-based shaft alignment solution

  • 10-meter range
  • When alignment is part of your PM program (if it is not, it should be).
  • When you expect bolt-bound or base-bound problems (Feet Lock feature), if your equipment has been in operation for many years, you have pipe strain issues, or your bases are not in good condition, you most likely have bolt-bound or base-bound problems.
  • When vibration from nearby machines cause challenges in performing precision alignment.
  • Thermal growth targets
  • Alignment of vertical machines.
  • Cloud access

General industrial machinery alignment, pumps, fans, compressors, etc.

AT-300

Next-generation digital line laser system redefining precision and productivity in measuring methods.

  • 15-meter range
  • When thermal growth needs to be measured (Hot Check)
  • Spacer shafts
  • Cardan shafts, or universal joints
  • Engines or other prime movers, especially those with more than 4 feet
  • Flywheels (magnetic base)
  • To check for runout on couplings or shafts, measure end play (thrust) or magnetic center, etc. (Run Out Probe)
  • Medium to large machinery, diesel engines, paper, steel, film, power generation, ships, etc.

AT-400

Achieve precision with the Acoem AT-400 high-end dual-axis shaft alignment system

  • 20-meter range
  • 2-axis live mode, for monitoring machinery, moves both vertically and horizontally simultaneously.
  • Multipoint, Sweep measurement modes
  • Micron-level accuracy, every time
  • Ultra-thin, lightweight portability
  • Protective design, built to last
  • Large detector, superior clarityIndustrial machinery installation, base plates, foundations, large or complex alignments, etc.
