The GUMMI A-350/200 flexible coupling is a power transmission component that connects two shafts and absorbs misalignments, vibrations and torsional shocks. Its rubber flexible center allows smooth and quiet operation, protecting machinery. It is used in industrial applications where high torque must be transmitted with some flexibility, such as mills, large-capacity pumps, fans and conveyors. MR Accesorios Industriales supplies this brand with more than 80 years of experience in the industry.
This GUMMI Type A coupling, model A-350/200, has a two standard hubs (CN) configuration. Its nominal torque is 118,750 Nm and it accepts a maximum bore of 200 mm, with a pilot bore of 120 mm. The flexible center has a diameter of 1130 mm, an overall length of 735 mm and a weight of 1049 kg. These characteristics position it as a robust solution for high-power transmissions that need to damp dynamic loads.
Typical applications for this coupling include mill drives, crushers, large centrifugal pumps, industrial fans and high-capacity conveyors. In all these cases, the GUMMI A-350/200 flexible coupling helps reduce vibration transmission and compensate for small misalignments between shafts, extending the service life of the associated bearings and gears. It is common in cement plants, mining, steelmaking and power generation.
To install this coupling, verify that the shafts have the appropriate diameter and keyway length for the maximum bore of 200 mm. The 120 mm pilot bore facilitates final machining. It is important to align the hubs as precisely as possible and to control the tightening torque of the fastening elements. Selection must consider the nominal torque of 118,750 Nm, the application service factor and environmental conditions. The rubber flexible center should be inspected periodically to detect wear or aging.

Frequently Asked Questions
- What does the CN configuration mean in this coupling?
- CN indicates two standard hubs, meaning both hubs are of standard design for mounting on shaft ends. This configuration is the most common and allows transmitting the nominal torque of 118,750 Nm with the flexibility of the rubber flexible center.
- What is the maximum bore that the GUMMI A-350/200 accepts?
- The maximum bore is 200 mm. The coupling comes with a 120 mm pilot bore that can be machined to the required size. It is essential that final machining be performed with adequate tolerances to ensure a correct fit and avoid vibrations.
- How do I request a quote or an equivalent?
- Write to us via WhatsApp at MR Accesorios Industriales with the code A-350/200 or the model you need. We will respond promptly with the quote and, if you are looking for a variant, we will advise you on the available options in the Type A series.
