Why is Precision Shaft Alignment Important?

Precision alignment pays off in many ways:

Reduced power consumption
Decreased wear on bearings, seals and couplings
Reduced unscheduled downtime
Reduced machinery vibration

Effects of Misalignment

Premature bearing, seal and coupling failures
Elevated bearing and coupling temperatures
Excessive vibrations
Loosening of bolts/ fasteners
High power consumption

Only 7% of measured machines within acceptable tolerances*

Benefits of Shaft Alignment

Reduced Production Downtime

Your plant/operation is not in business to perform maintenance. You have to satisfy your customers. Unscheduled downtime can be costly.

Reduced Maintenance Costs

Properly aligned machinery needs less unscheduled maintenance. It has also been proven that unscheduled maintenance is more expensive than planned maintenance (sometimes as much as 10X). Properly aligning your machinery will reduce your overall cost of maintenance.

Reduced Inventory Costs

When machines are properly aligned they require fewer parts replacements (bearings, couplings, seals, etc.). This can translate into reduced inventory of spare/replacement parts.

Increased Machinery Life

Misalignment will cause machines to vibrate excessively. The forces generated are not absorbed by the flexible coupling or the machine casing. The forces are transmitted to the bearings, and result in reduced bearing life. The forces can also damage seals.

The energy savings from alignment can be approximated in the field.

Where
kW = Three-phase power in kilo-Watts
V = RMS voltage, mean line-to-line of 3 phases
l = RMS current, mean of 3 phases
PF = Power factor as a decimal

What our Customers Say

We have started using a laser system for alignments because we have lost most of the personnel who were familiar with the dial indicator methods. Most of them have retired. The laser system makes it easier for the new personnel to do a good job, without the manual calculations or graphing.

Maintenance Manager

Containerboard Manufacturer

We use a laser system to check the work done by the installing contractors. It is fast and accurate. In addition, we can generate a report that is filed in our CMMS system. The laser system has helped us to avoid premature failures and warranty issues.
