GCH Form Flex Couplings
TB Wood's GCH Form-Flex couplings are designed to connect two shafts for efficient power transmission applications in screw compressors, cooling towers or printing presses. These couplings come in a robust disc pack design for greater torque loads and lower weight per HP for a better inherent balance, as compared to rigid couplings. The high torsional stiffness feature of these couplings maintains the structural integrity of the system while counterbalancing angular or axial misalignments. They are integrated with a fail-safe mechanism that gets activated, when the element is damaged, by simply transmitting rotary motion via washers.
