The GUMMI A-120/140 CX is a flexible coupling used to join two shafts in a drive line, absorbing minor misalignment, vibration and torque peaks. Its CX designation corresponds to an axial hub arrangement, intended for equipment in which the coupling cannot move along the shaft axis. It helps protect bearings, gears and other drive components from the loads that come with imperfect alignment. MR Industrial Accessories supplies this coupling to customers in the United States and several Latin American countries.

Reading the code is straightforward. The Type A series is identified by the model A-120/140, and the CX suffix marks the axial hub version. Shafts handled by this size range from 50 mm minimum to 102 mm maximum. Because the axial hub blocks movement in the shaft direction, this variant suits machines that must stay fixed axially. When placing an order, use the complete designation A-120/140 CX so it is not confused with other configurations in the same series.

These couplings appear in drives that need flexibility without axial play: pumps, fans, gear reducers, conveyors and general process equipment. They are also chosen where the assembly has to be axially restrained so the bearings of the driven machine are not loaded. In plant environments, they are common on production lines that must take up small angular or radial misalignment without passing vibration along the rest of the system.

Selection comes down to a few points: the diameters of the shafts being joined, the nominal torque and starting peaks of the machine, and the type of misalignment the coupling has to compensate. The CX version is the right pick when axial displacement is not permitted; if the equipment needs freedom in that direction, another configuration in the same series should be reviewed. During installation, align the hubs within the manufacturer's tolerances and use fasteners suited to the shaft diameter. Careful alignment helps the flexible element last.

If you are looking for an equivalent, send the code A-120/140 CX by WhatsApp or email, or share the model shown on the machine nameplate. A photo of the coupling along with your measured shaft diameters also helps. With that information, the technical team can identify the variant that fits your application and suggest alternatives when needed.
