Description
GUMMI A-400/400 belongs to flexible coupling, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for A-400/400 and any equivalents.
A high-torque flexible coupling from the GUMMI Type A line, the A-400/400 links two shafts while taking up angular and radial offset, vibration and torsional shock. It pairs two standard hubs (CN) with a rubber flexible center, and it is built for drives that call for a rated torque of 168,750 Nm and a maximum bore of 400 mm.
Reading the code helps when you compare it against the coupling on your equipment. The A-400/400 carries two standard hubs (CN), a 120 mm pilot bore and a flexible center measuring 1130 mm across. End to end it measures 1085 mm and weighs 2245 kg. Rated torque is 168,750 Nm. Within the elastic range of the rubber element, the coupling absorbs angular and radial misalignment.
Mill drives, crushers, high-flow pumps, industrial fans, and mining or cement equipment are the usual homes for this size. By softening torque peaks and cutting down the vibration that travels through the driveline, it helps protect bearings and gears on both sides of the coupling in continuous process lines.
Alignment of the two shafts should be checked before the hubs go on. The 120 mm pilot bore and the 400 mm maximum bore leave room to machine the final diameter to match your shaft. During installation, confirm the tightening torque of the fasteners and make sure the flexible center is not left permanently deformed. When selecting the coupling, work from the 168,750 Nm rated torque together with your service conditions, including shock loads or reversing duty.

Frequently asked questions
- What does the CN configuration mean on this coupling?
- CN stands for two standard hubs, so neither end uses a special flange. Both hubs can be machined to the shaft diameter, up to the 400 mm maximum bore.
- Can this GUMMI A-400/400 replace a coupling from another brand?
- An equivalent can be reviewed. Share the shaft dimensions, the working torque and the space available, and the team will advise on compatibility with the A-400/400.
- How do I ask about another size in the Type A series?
- The Type A series covers several sizes. Send the code or the torque and bore you need via WhatsApp or email and the matching option will be quoted.
