For drives that need both torque capacity and tolerance to misalignment, the GUMMI A-200/140 flexible coupling is a Type A unit built with two normal hubs (CN) and a rubber flexible center. It connects two shafts while damping vibration and torsional shocks, which makes it a common choice for heavy rotating equipment such as mills, pumps, fans and conveyors.
The A-200/140 is rated for a nominal torque of 25190 Nm and accepts a maximum bore of 140 mm. It is supplied with a 70 mm pilot bore, ready for final machining to match the shafts. The flexible center measures 550 mm in diameter, the coupling is 445 mm long overall and it weighs 202.4 kg.
In service, this coupling is found in cement, mining, steel and material processing plants. Typical pairings include ball mills, crushers, high-flow centrifugal pumps, industrial fans and high-load conveyors. By absorbing vibration and torsional shocks, it helps protect the bearings and gears connected to the drive and reduces corrective maintenance.
When selecting the A-200/140, check the torque required by the application, the shaft diameters and the operating environment. Alignment between the two shafts should be verified at installation: the coupling tolerates misalignment, but a poorly aligned drive will wear the flexible element faster. The 70 mm pilot bore can be machined up to the 140 mm maximum to suit the shaft, and the manufacturer's recommendations for bolt tightening torque and lubrication should be followed.
If you are looking for an equivalent within the Type A series, send us the torque, shaft dimensions and the configuration you need, and our team can help identify the right model. We also supply bearing housings, bearings, chains and other transmission components.

Frequently asked questions
- What is the nominal torque of the GUMMI A-200/140 coupling?
- The nominal torque is 25190 Nm. This is the value for normal operating conditions; where load peaks occur, a suitable service factor should be applied.
- What does the CN configuration mean on this coupling?
- CN means two normal hubs, the standard arrangement in the Type A series. The two identical hubs are joined through the rubber flexible center, so torque can be transmitted in either direction of rotation while angular and radial misalignment is absorbed.
- Can the bore be machined to fit my shaft?
- Yes. The coupling comes with a 70 mm pilot bore that can be machined up to a maximum of 140 mm to match your shaft dimensions. Use suitable tolerances and check alignment during mounting.
