A Flexible Coupling can also be known as elastic couplings. These couplings tend to have an elastic section between the ends of the coupling. A Flexible Coupling is unique in construction made specific to applications. A Flexible Coupling is designed to transmit torque while allowing radial, axial, and angular misalignment. A Flexible Coupling can compensate for angular misalignment up to a few degrees and some parallel misalignment.
A flexible coupling can protect machinery from wear and premature breakdown. A flexible coupling can play a large role in extending the life of a components attached to the coupling and at the same time, not degrading the performance of the machine. A proper flexible coupling fitting is sometimes overlooked but can be critical to machine design quality. Couplings are controlled by the driving force that it is connected to. A coupling only acts as an extension, transferring torque and speed from one component to another. More often than not a coupling will be connected to some type of driving force whether it is a stepper, brushless, brushed, AC, or servo motor.
