Laser Alignment
Laser alignment is a shaft-alignment method using optical measurement devices to calculate and guide machine-position corrections.
What this term means in maintenance
Laser alignment is a shaft-alignment method using optical measurement devices to calculate and guide machine-position corrections.
Benefits
Laser systems can provide:
- Accurate offset measurement
- Angular measurement
- Live machine movement
- Correction guidance
- Stored results
- Thermal-growth compensation
Practical example
A motor is adjusted horizontally and vertically until laser readings meet approved tolerance.
Preparation
Reliable alignment still requires checking soft foot, base condition, coupling, pipe strain, and machine movement.
Records
Before and after results can be attached to the maintenance work order.
Common mistake
Using an advanced laser tool without correcting soft foot or pipe strain produces unstable alignment.

Shaft Alignment
Shaft alignment is the adjustment of connected rotating-machine shafts so their centerlines operate within approved offset and angular tolerances.
Soft Foot
Soft foot is a condition where one or more machine feet do not sit evenly on the base, causing frame distortion when hold-down bolts are tightened.
Work Order Completion Evidence
Work order completion evidence is the recorded proof that maintenance was performed and the required result was achieved.
