ATB 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.

AHub City spline shafts are specially designed for transmitting high amount of torque force and rotation. These plain and involute splined shafts feature 1215 cold-rolled steel to deliver fair vibration damping and excellent chemical resistance. We also offer Hub City couplings in 1144 stress-proofed steel to connect and transmit torque between two rotating shafts. These couplers feature Kwik-D-Tach connection for safe and secure attachments.
OAL (overall length tolerance) refers to the allowable deviation from the nominal or desired length of the coupling. It helps to position and align the coupling on the shafts it is connecting.
Keyways are grooves or slots that are machined into the bore of the coupling hub and include a matching key that is installed in the keyway to connect the hub to the shaft. These keyways help transmit torque, ease installation and provide accurate alignment between the shaft and the coupling.
The choice of coupling depends on shaft misalignment, torque requirements, speed and environmental conditions.
Rigid couplings do not allow any angular or parallel misalignment between shafts. They provide a solid, backlash-free connection. In contrast, flexible couplings accommodate some degree of misalignment and are often used to dampen vibrations and shock loads in machinery.
External spline refers to the presence of the splines on the outside surface of a shaft, while internal spline refers to the splines inside a cylindrical bore.
Rigid couplings provide a solid connection with no flexibility, flexible couplings offer misalignment compensation, and fluid couplings use hydraulic principles for torque transmission and speed control.
