A flexible coupling from the GUMMI Type A line, the A-80/90 CX connects two shafts while absorbing vibration, load spikes and minor misalignment. Its CX designation means the hub is axial, so the shaft position stays fixed and no longitudinal travel is possible. That makes it a practical choice for driven equipment that has to stay put, such as pumps, fans, conveyors and other process machinery where torque is transmitted through frequent starts.
Reading the code helps with selection: Type A is the coupling family, A-80/90 is the size, and CX identifies the axial hub version. Published dimensions for this reference cover shafts from 30 mm up to 64 mm. Because the axial hub holds the shaft in place, this coupling suits assemblies where movement along the axis is not acceptable. The elastic element inside takes care of small angular and radial offsets and softens the vibration coming from the drivetrain.
You will find it on centrifugal pumps, fans, screw compressors, conveyors and machine tools. On those machines it shields the bearings and cuts down noise, particularly when the motor starts under load or when torque fluctuates. It also fits installations where the shaft cannot shift, such as single-suction pumps or equipment whose thrust bearings already set the position.
Selection follows a simple order. Start with the diameters of the two shafts and verify they fall inside the 30 to 64 mm range. Then look at motor power, speed and the nature of the load, since a pump and a system prone to water hammer do not behave the same way. The axial hub calls for solid shaft support and no longitudinal play in the assembly. Taking time to align everything correctly pays off in the service life of the elastic element.
For an equivalent, send the code A-80/90 CX or the model of the coupling being replaced. Shaft diameter and operating conditions are also useful, and our team will point you to the variant that matches.

Frequently asked questions
- What does CX indicate on the GUMMI A-80/90 coupling?
- CX stands for axial hub. The coupling locks the shaft position, so there is no longitudinal displacement. Choose it when the machine cannot allow axial movement, for instance a pump or equipment with thrust bearings that already control play.
- Which shaft sizes fit the GUMMI A-80/90 CX?
- The published dimensions for this reference cover shafts from 30 mm to 64 mm in diameter. If your measurement falls outside that window, send it to us on WhatsApp and we will identify the correct variant.
- How do I get a quote or an equivalent?
- Send the code A-80/90 CX by WhatsApp or email. For an equivalent, include the model of the coupling you are replacing plus the shaft dimensions. Our team replies promptly and can suggest alternatives and help with the selection.
