Description
GUMMI A-300/300 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-300/300 and any equivalents.
The GUMMI A-300/300 is a flexible coupling from the Type A series, built with two standard hubs (CN). It links shafts while compensating for misalignment and damping vibration and shock, which helps protect the connected machinery. This size is intended for drives that transmit high torque, and MR supplies it as part of its power transmission range for customers in the United States and Latin America.
The technical data for this unit list a nominal torque of 86120 Nm and a maximum bore of 300 mm. It is delivered with a 100 mm pilot bore. The flexible center measures 740 mm in diameter, the overall length is 786 mm, and the weight is 695 kg. These figures apply to the standard execution and should be checked against the actual application before ordering.
Because of its torque capacity and its ability to absorb vibration, this coupling is common in heavy-duty drives such as mills, crushers, high-capacity pumps and industrial fans, as well as in mining, cement, paper, steel and aggregate processing equipment. It also suits installations driven by electric or combustion engines that start under load.
When selecting the coupling, review the required nominal torque, the shaft diameters and the misalignment the drive will see. The 300 mm maximum bore is the limit for the hubs, while the 100 mm pilot bore is machined to the final shaft size. Concentricity and balancing deserve attention, particularly on high-speed drives, and installation should follow the proper tightening torques with suitable tooling.
If you are looking for an alternative, other configurations in the Type A series or couplings in different sizes can be reviewed. Send the code or model you need through WhatsApp or email, and the team will reply promptly with guidance and, where applicable, suggest equivalents.

Frequently asked questions
- What does the CN configuration mean on this coupling?
- CN stands for two standard hubs, so both ends use standard hubs without special flanges. This is the usual arrangement for connecting in-line shafts and allows direct mounting on machined shafts.
- What is the nominal torque of the GUMMI A-300/300?
- The nominal torque is 86120 Nm according to the manufacturer's specifications. This value should be considered together with the application service factor when selecting the coupling.
- Can I request a different bore size?
- Yes. The coupling comes with a 100 mm pilot bore and can be machined up to a maximum bore of 300 mm. Send the shaft diameter you need via WhatsApp or email and the team will provide a quote.
