Double-Flex Coupling
Use a double-flex coupling whenever two shafts are joined with parallel misalignment, or a combination of
angular and parallel misalignment (the most common situation).
Single-flex and double-flex couplings may or may not accept end play, depending on their design.
Rigid Coupling
Rigid couplings are generally not recommended, because they cannot compensate for any misalignment. They
should be used only if the motor or load is on some form of floating mounts that allow for alignment
compensation. Rigid couplings can also be used when the load is supported entirely by the motor’s bearings.
A small mirror connected to a motor shaft is an example of such an application.
