Description
GUMMI A-120/120 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-120/120 and any equivalents.
For medium and high power drive lines, the GUMMI A-120/120 flexible coupling links two shafts while damping vibration and accommodating minor misalignment. Its rubber flexible center smooths out starts and fluctuating loads. You will find it on pumps, fans, compressors and conveyors, among other industrial equipment.
The A-120/120 sits in the Type A series of GUMMI couplings and ships in the CN configuration, meaning two standard hubs. Key figures: rated torque 4940 Nm, maximum bore 120 mm, pilot bore 45 mm, flexible center diameter 403 mm, overall length 380 mm, weight 86 kg. Those values make it a solid pick for demanding transmissions.
Typical duties include centrifugal pumps, industrial fans, screw compressors, conveyor belts and mills. In each case the rubber element absorbs torsional vibration and takes up small shaft misalignments, which helps limit wear on bearings and seals and keeps the assembly running longer.
When selecting the coupling, check the machine's rated torque, the shaft diameters and the rotation speed. The 120 mm maximum bore and 45 mm pilot bore let you machine the hubs to the final shaft size. Confirm alignment at assembly and use the correct fasteners to avoid parasitic loads.

Frequently asked questions
- What does the CN configuration mean on this coupling?
- CN means two standard hubs: both sides are identical and are machined to fit the shafts. It is the most common setup and allows mounting in any position, always within the stated maximum bore and pilot bore.
- Can I machine the hubs to a different size?
- Yes. The coupling comes with a 45 mm pilot bore and can be machined up to a maximum bore of 120 mm. Machine with adequate tolerances and verify alignment to protect the flexible element's service life.
- How do I request a quote or an equivalent?
- Write on WhatsApp with the part number A-120/120 or your shaft dimensions and required torque. The team will help you find the right variant in the Type A series or an equivalent that suits your equipment.
