Description
GUMMI A-60 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-60 and any equivalents.
A flexible coupling from the GUMMI Type A line, the A-60 joins two shafts while its rubber center damps vibration and absorbs torque peaks and minor misalignment. That damping action helps protect bearings, gears and the surrounding machine frame, which makes the coupling a practical choice for pumps, fans, conveyors and similar process drives where a simple, serviceable connection is preferred.
The A-60 comes in the two standard hub configuration, designated CN, with a rubber flexible center. Key figures for selection: flexible center diameter 224 mm, overall assembly length 185 mm, weight 12.5 kg, rated torque 620 Nm, maximum bore 55 mm and pilot bore 25 mm. The pilot bore is supplied undersized so it can be machined to the actual shaft diameter and keyed to standard. In size terms this is a mid-range coupling, suited to drives running moderate loads that call for damping.
You will find it on centrifugal pumps, fans, blowers, screw compressors, belt and elevator drives, as well as mixers, mills and other process equipment where start-up produces torque peaks. In each case the rubber center limits how much vibration reaches the frame and compensates small angular, radial and axial offset between the shafts.
Selection starts with the working torque of the drive: it must stay within the 620 Nm rating. Confirm next that the 55 mm maximum bore covers your shaft diameter, then machine the 25 mm pilot bore to final size with the keyway. At assembly, align the hubs with a straightedge or dial indicator before tightening, keep the axial clearance the manufacturer specifies, and never force the flexible center into place.
Inspect the rubber element at every shutdown. Cracks or hardening mean it is time to replace the center. If your application needs a different bore or a brake hub configuration, send the A-60 part number or the model you have, along with shaft diameter, torque and working rpm, by WhatsApp or email. The team can also check equivalences against other rubber-center flexible coupling lines and suggest the variant that fits your machine.
MR Industrial Accessories LLC supplies the GUMMI line alongside bearings, mounted units and housings, power transmission components, seals, lubrication and maintenance tools, serving customers across the United States, Canada, Mexico and South America.

Frequently asked questions
- What configuration does the GUMMI A-60 coupling have?
- It is a flexible coupling from the Type A series with two standard hubs (CN) and a rubber center. The flexible center measures 224 mm in diameter, the assembly is 185 mm long overall and weighs 12.5 kg. Rated torque is 620 Nm and maximum bore is 55 mm.
- How do I request a different size or an equivalent?
- Send the part number A-60, or the model you need, by WhatsApp or email together with the shaft diameter, torque and working rpm. With that information the team can point you to the right variant in the Type A series or an equivalent from another flexible coupling line.
- What should I check before mounting it?
- Make sure the machined bore matches the shaft diameter and that the working torque stays within 620 Nm. Align the hubs with a straightedge or dial indicator, respect the specified axial clearance, and inspect the rubber: cracks or hardening call for replacement.
