Causes Of Misalignment

Thermal expansion - Most machines align cold.

Machine vibrations.

Forces transmitted to the machine by pipe or

 support structure.

Soft foot.

Direct coupled machined are not properly aligned.

Poor workmanship.

Effects Of Misalignment

More than 50% problems are due to misalignment.

Causes vibration on the machine

Vibration destroys critical parts of machines like bearings, gears, seals, coupling etc.

Breaks lubricant film inside the bearing and increase friction.

Increases load on the bearing.

Increase 2 - 17% power consumption.

Generates heat inside the coupling.

Types Of Misalignment
