The GUMMI A-120/140 CX flexible coupling is a power transmission component that connects two shafts and absorbs slight misalignment, vibration and torque peaks. Its axial hub configuration (CX) is designed for machines that do not allow axial displacement, where the coupling must be fixed in that direction. It is used in transmission equipment where the goal is to protect bearings, gears and other elements of the drive line. MR Accesorios Industriales sells it in Buenos Aires, Argentina, with more than 80 years of experience in industrial distribution.

This GUMMI Type A coupling is identified with the model A-120/140 and the CX variant, which corresponds to an axial hub configuration. It accepts shafts with a minimum diameter of 50 mm and a maximum of 102 mm. The axial hub restricts movement in the shaft direction, so it is the indicated option when the equipment must not shift axially. The full commercial designation is A-120/140 CX and it is best to order it that way to avoid confusion with other variants of the same series.

Typical applications of this coupling appear in machines where the transmission must be flexible but without axial play: pumps, fans, gear reducers, conveyor belts and process equipment in general. It is also used in drives where the assembly requires the unit to be axially fixed so as not to load the bearings of the driven equipment. In industrial plants, it is common to find it in production lines that need to absorb small angular or radial misalignments without transmitting vibrations to the rest of the system.

To correctly select the coupling, take into account the diameter of the shafts to be connected, the nominal torque and the starting peaks of the machine, and the type of misalignment it must compensate for. The CX variant is chosen when axial displacement is not allowed; if the equipment needs freedom in that direction, it is best to evaluate another configuration of the same series. Installation must be done with the hubs aligned within the manufacturer's tolerances and with the fastening elements suitable for the shaft diameter. Careful alignment extends the service life of the flexible element.
