Description
GUMMI A-50 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-50 and any equivalents.
The GUMMI A-50 flexible coupling joins two shafts while its rubber element absorbs vibration and torsional shock. It also tolerates slight misalignment and cuts noise transmission. You will find it on pumps, fans, compressors and conveyors. This model belongs to the Type A series and comes with two standard hubs, making it suitable for both replacements and new installations.
The A-50 uses the two standard hubs (CN) arrangement. Its elastic center measures 167 mm across, and the assembled coupling is 140 mm long. Rated torque is 420 Nm, and each hub accepts a shaft up to 46 mm. A 15 mm pilot bore is provided so the final diameter can be machined to match the shaft. The coupling weighs 5.32 kg. These figures together describe how much power it can transfer while damping.
This coupling suits drives that need to absorb vibration and minor misalignment. It appears on centrifugal pumps, fans, screw compressors, conveyors and machine tools, as well as on equipment in mining, cement and treatment plants. The rubber center softens impulsive loads, which helps the bearings and gears it connects last longer.
When selecting an A-50, confirm that the application torque stays within 420 Nm and that the shaft diameter does not go above 46 mm. The 15 mm pilot bore must be machined to the required size with the correct tolerance and keyway. Take care with shaft alignment so the elastomer is not stressed. For reversing rotation or pulsating loads, apply a service factor.
If you need a different configuration, such as hubs with brake or flange, or a higher-capacity model, we can suggest alternatives from the GUMMI line. We can also help you replace it with a coupling from another brand that offers equivalent performance. Send the code A-50, or your shaft dimensions and required torque, through WhatsApp or email.

Frequently asked questions
- What does the CN configuration mean on the A-50 coupling?
- CN stands for two standard hubs. Both hubs are identical and mount on the shafts, with the rubber center between them transmitting torque and damping vibration. This is the usual setup for most applications.
- Can the pilot bore be machined to a larger diameter?
- Yes. The 15 mm pilot bore can be machined up to the 46 mm maximum bore. The machine shop must hold the proper tolerance and cut the keyway to standard. Do not exceed the maximum diameter, as that would weaken the hub.
- How do I request a quote for the A-50 or an equivalent?
- Write to us via WhatsApp or email with the code A-50 and the quantity you need. If you want an equivalent from another brand, send the equipment data: torque, shaft diameter and speed. We will reply promptly with the options.
