The GUMMI A-120 CI flexible coupling is a power transmission component that connects two shafts and absorbs misalignment, vibration and torque peaks. Its integral hub (CI) configuration makes it suitable for larger diameter shafts, with a maximum bore of 170 mm. It is used in equipment where continuous operation and machine protection are required. MR Accesorios Industriales supplies this model with the backing of more than 80 years in the field.
This item is a flexible coupling from the GUMMI Type A series, model A-120, with an integral hub (CI) configuration. Integral hub means the hub and flange form a single piece, which simplifies mounting and adds rigidity. The maximum permissible bore is 170 mm, so it is intended for large diameter shafts. The designation A-120 CI identifies the size and construction variant within the line.
Typical applications of this coupling include heavy drives in mills, conveyor belts, high-flow pumps, industrial fans and continuous process machines. Its ability to compensate for angular and radial misalignment reduces wear on bearings and seals. In plants where starting torque is high, the elastic element dampens shocks and protects the rest of the system. It is a robust solution for environments with variable loads and demanding service.
To select the coupling correctly, check the shaft diameter, nominal and maximum torque, and operating speed. The maximum bore of 170 mm defines the limit for this model; if the shaft exceeds that size, you must move up to a larger size. Mounting requires precisely aligning the shafts before tightening the hubs, and checking the tightening of the fastening elements according to the manufacturer's instructions. Lubrication and the condition of the elastomer affect service life.

Frequently Asked Questions
- What does the CI configuration mean on the GUMMI A-120 coupling?
- CI means integral hub: the hub and flange are a single piece. This simplifies mounting and adds greater rigidity to the assembly. It is a variant designed for larger diameter shafts, as in the case of this model with a maximum bore of 170 mm.
- What is the maximum bore this coupling accepts?
- The maximum bore is 170 mm. If your shaft exceeds that size, you need to select a larger size within the same line. Message us on WhatsApp with your shaft diameter and we will guide you toward the right option.
- How do I request a quote or an equivalent?
- Send the code A-120 CI by WhatsApp along with your shaft dimensions and working conditions. We will reply shortly with the quote and, if needed, with equivalent alternatives within the Type A series.
