Laser Shaft Alignment

Pump and Motor

Laser alignment to date is the most accurate way to check and realign all types of rotating coupled units, as opposed to the old methods of Straight edges and dial indicators.

Laser shaft alignment should be applied on all rotating equipment to eliminate problems such as:

Overloads and vibrations
Bearing wear and failure - due to excessive torque.
Wear and failure of seals.
Excessive power consumption - which can increase by as much as 20% on misaligned units.
Metal fatigue on shafts and journals due to excessive misalignment stresses.
Vibration

Even in instances where flexible couplings are used it is proven fact that the same stresses occur in the Bearings and shafts.

Typical Applications:

Normal shaft - shaft / coupled units.
Gearbox / pump - motor
Drive trains
Drive shafts / line shafts
Direct drives (direct roll drives)
Offset drives / cardan shaft coupled offsets

Most manufacturers specify recommended tolerances, which should be applied, the following table lists the general Alignment tolerance guidelines.

Alignment Tolerences

Rotation Speed
rpm
Angular MisalignmentParallel Misalignment
mm/100mm0.001"/1"mm0.001"
0-10000.101.00.135.1
1000-20000.080.80.103.9
2000-30000.070.70.072.8
3000-40000.060.60.052.0
4000-50000.050.50.031.2

*These tolerances cannot be achieved using the Straightedge / DTI methods.

Benefits:

By correctly and accurately laser aligning shafts / couplings etc, you will remove all the above problems normally associated with poor misalignment which is why our system proves both cost effective and maintenance friendly.
