The GUMMI A-155/155 flexible coupling is a power transmission component that connects two shafts and absorbs misalignments, vibrations and torque peaks. Its rubber flexible center allows smooth and quiet operation, protecting the connected equipment. It is used in industrial applications where high loads must be transmitted with some flexibility, such as mills, conveyor belts, pumps and fans. MR Accesorios Industriales sells this brand with more than 80 years of experience in the field.

This GUMMI Type A coupling, model A-155/155, is configured with two standard hubs (CN). It withstands a nominal torque of 9750 Nm and accepts a maximum bore of 155 mm. The pilot bore is 50 mm, the flexible center diameter is 470 mm and the total length reaches 440 mm. Its weight is 126 kg. These characteristics position it as a robust option for demanding transmissions.

Typical applications include mill drives, crushers, conveyor belts, centrifugal pumps, fans and industrial mixers. In all cases, the flexible coupling compensates for angular and radial misalignments, dampens torsional vibrations and reduces the transmission of shock loads, extending the service life of the associated bearings and gears.

To correctly select this coupling, take into account the required nominal torque, the diameter of the shafts to be connected and the service conditions. The maximum bore of 155 mm and the pilot bore of 50 mm allow the hubs to be machined to the final dimensions. It is important to verify alignment during assembly and use the appropriate fastening elements to avoid parasitic stresses.

If you need an equivalent or a nearby size, you can consult us with the part number or the dimensions of your application. We advise you on finding the best alternative within the GUMMI line or from other brands we carry. MR Accesorios Industriales has a technical team to help you define the best solution.

Frequently Asked Questions

What does the CN configuration mean in this coupling?
CN indicates two standard hubs, meaning both hubs are of standard design. This configuration is the most common and allows two shafts to be connected with the rubber flexible center between them.
What is the nominal torque of the A-155/155 coupling?
The nominal torque is 9750 Nm, according to the manufacturer's specifications. This value is a guide and should be considered together with the application's service factor to select the appropriate coupling.
Can I machine the hubs to a different size?
Yes, the coupling is supplied with a pilot bore of 50 mm and accepts a maximum bore of 155 mm. The hubs can be machined up to that size according to the diameter of the shafts to be connected.
