The Basics of Laser Shaft Alignment

What is Laser Shaft Alignment and How Does it Work?

Laser shaft alignment is a method of aligning rotating machinery components such as motors, pumps, and fans. It uses lasers to measure the misalignment between two or more components in order to ensure that they are properly aligned for optimal performance. This process helps reduce vibration, noise, and wear on the components, resulting in improved energy efficiency and longer life span of the machinery. By accurately measuring these misalignments and correcting them accordingly, laser shaft alignment can help improve the overall reliability of your equipment.

Why is Laser Shaft Alignment Essential for Machinery Operation?

Laser shaft alignment is an essential process for the proper operation of any machinery. It helps to ensure that the machinery is running smoothly, efficiently, and safely by providing precise alignment of its components. Laser shaft alignment also helps to reduce maintenance costs and downtime by ensuring that all parts are correctly aligned. This process can be used on a variety of machines, such as pumps, motors, compressors, and generators. By using laser shaft alignment techniques, it is possible to detect misalignments in machinery quickly and accurately in order to prevent costly repairs or replacements.

What are the Different Types of Laser Shaft Alignments Available?

There are several different types of laser shaft alignment available, each with their own unique advantages and disadvantages. In this article, we will discuss the different types of laser shaft alignment systems, their benefits and drawbacks, and how they can be used to improve machine performance.

1) Displaceable pinsThe simplest type of laser shaft alignment is the use of a displacement pin. In this system, the entire assembly of gears and pinions is mounted to a shaft with an offset. This type of adjustment requires that you precisely measure and mark both the carriage-mounted gear and displaced gear before removing them from the machine. Displaced pins are typically used for fine adjustments that do not require any other machinery.

2) Surface-mounted gearsThe surface-mounted gear system is a variation on the displacement pin design. In this case, rather than using an offset shaft, a single gear is mounted to the face of the carriage and the other gear sits on top of it. The assembly is adjusted using a screwdriver or wrench to move one side of each gear against its mating surface. This type of adjustment typically requires that you remove two gears from the machine before making your adjustment, then replace them after making your adjustment. Surface-mounted gears are generally used for larger adjustments in which it is preferable to avoid having to reassemble parts before and after the alignment.


Laser shaft alignment is a process of measuring and correcting misalignments in rotating machinery. It is a critical part of any industrial maintenance program, as it ensures that machines are running smoothly and efficiently. Laser shaft alignment systems provide the most accurate results for determining the exact position of the shafts in relation to each other. Check out laser shaft alignment for more information.
