The GUMMI A-140 CI flexible coupling is a power transmission component that connects two shafts and absorbs misalignments, vibrations 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 requiring flexible and reliable transmission, such as pumps, fans, compressors and conveyors. MR Accesorios Industriales supplies this model with technical assistance to select the correct size.

This coupling belongs to the GUMMI Type A series and is identified by the model A-140. The CI variant corresponds to an integral hub configuration, designed to mount on larger diameter shafts. According to the series data, the maximum allowable bore is 170 mm. The integral hub design simplifies mounting and adds rigidity to the assembly. To confirm other dimensions such as hub length, outer diameter or nominal torque, consult the manufacturer's tables for the Type A series.

Typical applications of this flexible coupling include drives in centrifugal pumps, industrial fans, screw compressors, conveyor belts and mixers. Its ability to compensate for angular and radial misalignments reduces wear on bearings and seals in the connected equipment. It is commonly found in process plants, mining, cement and water treatment, where operational continuity and low maintenance are required. Selecting the right flexible element allows the coupling to be adapted to different torque and speed conditions.

To correctly mount a GUMMI A-140 CI coupling, verify that the shaft diameters do not exceed the maximum bore of 170 mm and that the keys match the hub slots. It is essential to align the shafts before tightening the fastening elements; poor alignment accelerates wear of the elastomer. During selection, consider the nominal and maximum torque of the drive, the revolutions per minute and the working environment. If you need guidance, the technical team at MR Accesorios Industriales can help you validate the choice.

If the A-140 CI model does not suit your application, we can offer alternatives within the same Type A series or other flexible coupling lines. To request an equivalent or a nearby size, write to us on WhatsApp with the code A-140 CI or with your shaft dimensions and the type of machine. You can also indicate the shaft diameter, the distance between shaft ends and the required torque. With that data, we will send you a proposal shortly.
