For drives that need to connect two shafts while softening vibration and minor misalignment, the GUMMI A-170/170 flexible coupling uses an elastic rubber center between two standard hubs (CN). It belongs to the Type A series and is built for equipment where keeping the line running and holding dynamic loads down matters. MR Industrial Accessories supplies this coupling to customers throughout the United States and Latin America, and can help you confirm the right size for your application.
The A-170/170 code identifies a Type A coupling with two standard hubs, or CN. Its published ratings list a nominal torque of 14630 Nm. Shafts can be machined to a maximum bore of 170 mm, and the coupling arrives with a pilot bore of 120 mm. The elastic center measures 550 mm in diameter, the overall length is 545 mm, and the unit weighs 242.8 kg. Those figures suit heavy-duty transmission work.
You will find this size in mill drives, conveyor belts, high-flow pumps, industrial fans, and mining or cement equipment. In each case, the rubber center takes up small shaft misalignments and reduces the vibration and torque spikes that reach bearings, gears and structures. That is why it appears in installations where reliability and low maintenance are priorities.
Before mounting, check that each shaft diameter falls within the maximum bore range and that the hub length fits the space you have. The pilot bore is there to be machined to the final size. Align the shafts carefully before joining them, then verify the tightening torque on the fasteners. When selecting the coupling, look at nominal torque, peak loads and the environment it will run in. A correct installation keeps operation smooth over time.
If you need a different bore, more or less torque capacity, or another hub arrangement, ask us. We handle the GUMMI Type A line and can point you to the variant that fits your drive. To request an equivalent, send code A-170/170 or your dimensions and required torque by WhatsApp or email. Our team replies promptly with the technical information you need.

Frequently asked questions
- What does the CN configuration mean on the GUMMI A-170/170 coupling?
- CN stands for two standard hubs. Both hubs are the standard design without special modification, which is the most common setup and allows direct mounting on the shafts at the required bore.
- What is the nominal torque of the A-170/170 coupling?
- The nominal torque is 14630 Nm according to the manufacturer's specifications. Use this value together with peak loads and service conditions when selecting the coupling.
- Can I request a coupling with a bore different from the maximum of 170 mm?
- Yes, the coupling can be machined up to a maximum bore of 170 mm. If you need a specific size, contact us on WhatsApp with the required shaft diameter and we will advise you.
