The GUMMI A-350 CI is a flexible coupling from the Type A line that links two shafts while compensating for misalignment, vibration and shock. Its integral hub, identified by the CI suffix, is a one-piece design intended for larger shaft diameters, as listed in Table IV of the GUMMI Type A catalogue. It helps protect bearings and gears in drives that run continuously.

The code A-350 CI tells you two things: the size within the Type A series and the hub style. CI means the hub is machined as a single piece rather than split, which gives a more rigid connection when the shaft diameter calls for it. Since no separate flanges are needed, the coupling takes up less space during assembly.

You will find this coupling on machine tool drives, centrifugal pumps, industrial fans, conveyor belts and other continuous process equipment. In each case it absorbs small angular and radial offsets and softens shock loads before they reach the bearings. Food, chemical and aggregate plants often specify it because it handles washdown and outdoor conditions well.

When selecting a Type A coupling, check shaft diameter, nominal and maximum torque, speed and allowable misalignment. Choose the integral hub when the shaft is larger than the split-hub range. Make sure the flexible element suits the ambient temperature and any chemicals present. Align the shafts within the tolerances given by the manufacturer to prevent unnecessary stress.

If you need a replacement or an equivalent, send the part number A-350 CI or the data from the equipment nameplate. Other Type A variants are available with split or integral hubs to match your application. The flexible element and the hubs can also be quoted as separate items.
