Diaphragm Couplings

Couplings are mechanical fasteners, usually used to join two pieces of a shaft together for the purpose of driving rotating equipment. Many shaft coupling are designed for tight tolerances and require very accurate shaft alignment. A diaphragm coupling is a type of flexible coupling that makes use of a pair of flexible plates joined by a spacer to transfer torque from one plate to the other. The flexibility of the diaphragm plates allow for slight misalignments.
