The GUMMI A-80/90 CX flexible coupling is a power transmission component that connects two shafts and absorbs misalignment, vibration and load peaks. Its axial hub configuration (CX) 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 degree of flexibility.

This GUMMI Type A coupling, model A-80/90, is identified by its axial hub configuration (CX). 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 the longitudinal movement of the shaft, so it is suitable for assemblies where the equipment must not shift. The flexible part of the coupling compensates for small angular and radial misalignments, and dampens the vibrations 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 there are torque variations. 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 connected and confirm that 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 that the shaft be well supported and that the assembly does not leave longitudinal play. Careful alignment during installation extends the life of the flexible element.
