A Type A flexible coupling from the GUMMI line, the A-200/200 joins two shafts through a rubber center that takes the load in compression. It is built for drives where torque peaks and vibration need to be absorbed before they reach the rest of the train, and it comes assembled with two normal hubs, identified as CN. MR Industrial Accessories LLC supplies this coupling to maintenance and purchasing teams in the United States and Latin America, and can review the part number with you before you commit to an order.

Reading the code helps when you compare it against what is already installed. The nominal torque of this size is 25,190 Nm. Machining can go up to a maximum bore of 200 mm, while the pilot bore as supplied is 120 mm. The rubber flexible center measures 550 mm across, the assembly is 545 mm long overall, and the unit weighs 276.8 kg. Those figures are what you need on hand when checking whether the coupling fits the space and the shaft ends you have.

These couplings turn up in low and medium speed drives that see changing loads. Mills, crushers, high-flow pumps, industrial fans, conveyor belts and mixers are common examples. Another frequent case is equipment whose startup produces a torque spike: the rubber element takes that spike instead of passing it on to gears or bearings. Small angular and radial misalignment between the two shafts is also absorbed by the rubber center.

Selection comes down to three checks. First, take the working torque and apply the service factor that matches the application. Second, confirm the shaft diameters and the length available on both sides, remembering that the 200 mm maximum bore and the 120 mm pilot bore set the range you can machine to. Third, decide on the hub arrangement: CN means two normal hubs, which covers most installations, but if your setup calls for something different it is worth confirming before the order is placed.

If A-200/200 is not the size you need, other models in the same Type A series may fit. Send the part number you are replacing, the torque the drive requires, the shaft diameters and a photo of the assembly through WhatsApp or email. With those details the team can point you to an equivalent and help you settle on the right configuration.

For buyers working from an existing bill of materials, the fastest route is to send the part number as written. If a variant is involved, or if the drawing and the nameplate disagree, the team can look at both and confirm which one applies to your equipment.
