What is laser shaft alignment?

Shaft alignment is a procedure, also commonly known as coupling alignment, which aims to make two or more rotating shafts “line-up” or become co-linear, vertically and horizontally. The procedure can be achieved using various methods and tools such as optics, calipers, and lasers and so on, but, laser shaft alignment remains the most precise and fastest of them all.

Using laser technology for shaft alignment remains the best way to ensure that the two coupled shafts will continue to rotate on their common centerline. This effectively prevents troublesome misalignment problems in industrial machinery.

Benefits and uses of laser alignment in heavy industry.

As the name suggests, this procedure is used to align shaft in machinery. You may wonder why this is so important. Realize that just about any kind of machine you can imagine will record some sort of downtime or even significant damage once there is any slight misalignment. This cuts across almost every kind of industrial application imaginable and includes motors, gearboxes, couplings and pumps of whatever size and function. Allowing these machines to continue in operation will lead to inefficiency and eventually safety problems for the operators and technicians using them.

It’s been estimated that at least a third of all bearing failures can be traced to misaligned shafts alone in rotating machinery. Vibrations, wear and tear and complete system failure can be avoided by getting alignment – whether angular or offset – right.

Other benefits of laser shaft alignment include:

  • – It reduces friction.
  • – The light beams are not affected by gravity.
  • – Increases machinery uptime and efficiency.
  • – Laser systems can measure both vertically and horizontally oriented machines.

– Some systems allow the users store the desired alignment values digitally. This is priceless for maintenance records and referencing at a later stage.

– With time, inefficient machines will consume more energy to operate. Proper shaft alignment will prevent this problem.

– It ultimately reduces maintenance costs dramatically.

With the obvious benefits of laser systems for shaft alignment, it’s no wonder so many engineers are now adopting this technology in their own industries. You should too.
