INSTALLATION & ALIGNMENT DATA
Maximum life and minimum maintenance for the coupling
and connected machinery will result if couplings are
accurately aligned. Coupling life expectancy between initial
alignment and maximum operating limits is a function of
load, speed and lubrication.
Values listed are based upon the use of standard
coupling components, standard assemblies and
cataloged allowable speeds.
Values may be combined for an installation or operating condition.
Example: 1060T max. operating misalignment is .016"
parallel plus .018" angular.
NOTE: For applications requiring greater misalignment, refer
application details to the Factory.
Angular misalignment is dimension X minus Y as illustrated
below.
Parallel misalignment is distance P between the hub center
lines as illustrated below.
End float (with zero angular and parallel misalignment) is the
axial movement of the hubs(s) within the cover(s) measured
from “O” gap.
