Coupling Misalignment<br />

Maximum life and minimum maintenance for the coupling<br />

and connected machinery will result if couplings are<br />

accurately aligned. Coupling life expectancy between initial<br />

alignment and maximum operating limits is a function of<br />

load, speed and lubrication. For applications requiring<br />

greater misalignment, refer application details to Falk.<br />

Angular misalignment is expressed in degrees and as the<br />

difference between the value of X minus Y, as illustrated.<br />

Parallel misalignment is the distance P between shaft center<br />

lines as shown.<br />
