The GUMMI A-400 CI flexible coupling is a power transmission component that joins two shafts and absorbs misalignment, vibration and torque peaks. Its integral hub (CI) configuration makes it suitable for larger shaft diameters, where robust fastening and direct mounting are required. It is used in industrial equipment that needs operational continuity and protection of the drivetrain. MR Accesorios Industriales offers this model as part of its GUMMI coupling line.

This item is the GUMMI A-400 flexible coupling, with integral hub (CI) configuration. The integral hub means the shaft fastening element is machined in a single piece with the coupling body, which provides rigidity and simplifies mounting on larger shaft diameters. The A-400 CI designation identifies this variant within the GUMMI Type A series. To confirm dimensions, tolerances and torque capacity, consult the manufacturer's data sheet or request it from MR Accesorios Industriales.

Typical applications of this coupling include drives in centrifugal pumps, industrial fans, conveyor belts, mixers and mills. In all these machines, the flexible coupling transmits motion between the motor and the driven machine, compensating for small angular, radial and axial misalignments, and dampening torsional vibrations generated during startup or by load fluctuations.

To correctly select a GUMMI A-400 CI coupling, take into account the shaft diameter, the nominal and maximum torque of the drive, the revolutions per minute and the type of load. The integral hub requires verifying that the shaft diameter is compatible with the machined bore and that the keyway matches. During mounting, it is essential to align the shafts to the tolerance recommended by the manufacturer and to use the appropriate fastening elements to avoid parasitic stresses.

If you need an equivalent or a nearby size within the Type A series, you can message us on WhatsApp with the part number or model you are looking for. At MR Accesorios Industriales we guide you to find the variant that best suits your application, whether by shaft diameter, hub configuration or elastomer type. We can also advise you on other GUMMI models if this one does not exactly match what you need.
