The GUMMI A-80/90 CX flexible coupling is a power transmission component that joins two shafts and absorbs misalignment, vibration and load peaks. Its axial hub (CX) configuration is designed for machines that do not allow axial displacement, because it fixes the position of the assembly. It is used in pumps, fans, conveyor belts and process equipment where torque must be transmitted with frequent starts and a certain amount of flexibility.

This GUMMI Type A coupling, model A-80/90, is identified by its axial hub (CX) configuration. It accepts shafts with a minimum diameter of 30 mm and a maximum of 64 mm, according to the dimensions published for this reference. The axial hub restricts longitudinal shaft movement, so it is suitable for assemblies where the equipment must not shift. The elastic part of the coupling compensates for small angular and radial misalignments, and dampens the vibration generated by the transmission.

Typical applications include centrifugal pumps, fans, screw compressors, conveyors and machine tools. In these machines the coupling protects the bearings and reduces noise, especially when the motor starts under load or when torque varies. It is also used in installations where the shaft cannot move axially, such as single-suction pumps or equipment with thrust bearings that already fix the position.

To select the coupling, first check the diameter of the shafts to be joined and confirm they are within the 30 to 64 mm range. Then review the motor power and speed, and the type of load: a pump is not the same as equipment with water hammer. The axial hub requires the shaft to be well supported and the assembly to have no longitudinal play. Careful alignment during installation extends the life of the elastic element.
