For drives that need to connect two shafts while absorbing misalignment and vibration, the GUMMI A-200/90 flexible coupling is a solid choice. It uses two normal hubs (CN) and a rubber center to handle torque peaks and protect both the driving and driven equipment. This coupling is commonly found in pumps, fans, conveyors and other industrial machines.
The A-200/90 coupling belongs to the GUMMI Type A line. Its flexible rubber center measures 550 mm in diameter, and the overall length is 385 mm. The unit weighs 192.6 kg. It is rated for a nominal torque of 25,190 Nm. The maximum bore is 90 mm, and it comes with a pilot bore of 40 mm. These values are taken from Table III of the manufacturer's catalog and define its capacity for demanding power transmission.
You will see this coupling in centrifugal pump drives, industrial fans, belt conveyors, mills and mixers. The rubber center dampens torsional vibrations and compensates for moderate angular and radial misalignment. That reduces wear on bearings and seals in the connected equipment. It is a robust solution for chemical, food, mining and aggregate processing plants.
When selecting the coupling, consider the required nominal torque, the shaft diameters and the space available. The 40 mm pilot bore can be machined up to the 90 mm maximum to fit your shafts. Make sure the misalignment stays within the limits for the flexible element and that starting torque does not exceed the nominal torque. Proper alignment and fit will help extend the service life of the rubber.

Frequently asked questions
- What does the CN configuration mean in this coupling?
- CN stands for two normal hubs, meaning both sides of the coupling are identical and are machined to fit the shafts. This is the standard configuration for Type A and allows the flexible center to be mounted between both hubs.
- Can I modify the bore of the A-200/90 coupling?
- Yes, the coupling is supplied with a 40 mm pilot bore and can be machined up to a maximum bore of 90 mm. Proper tolerances are important to ensure a correct fit on the shaft.
- How do I request a quote for this coupling?
- Write to us on WhatsApp with the code A-200/90 or the model you need. Our team replies promptly with the information so you can move forward with your request.
