The Gummi Type A AV is a rubber-center elastic coupling built for high-speed duty and dynamically balanced. Its flexible tire element handles angular, radial and axial misalignment while damping torsional shocks, which takes load off bearings and cuts vibration in the motor-machine train. Ordering uses three pieces of information: model, AV code and rotation speed. MR Industrial Accessories LLC quotes this coupling for customers across the US, Canada, Mexico and South America.

Among Gummi rubber-center couplings, the Type A is the most widely recognized. The rubber element behaves like a tire: it accepts angular, radial and axial offset and absorbs the torsional peaks the motor sends through the driveline. The AV version adds dynamic balancing, which is what allows the coupling to run at elevated speeds. To read the designation, take the line letters AV together with the model that matches the size, then add the rotation speed to pin down the exact configuration.

Typical installations pair electric motors with centrifugal pumps, fans, blowers, screw compressors and other fast-rotating process equipment where the transmission needs smoothing. Machine tools, conveyors and agitators also use this coupling when vibration between the motor and the driven machine should be isolated. Because the element is elastic, the rubber takes up the small misalignments that appear during assembly and as bases settle.

Selecting a Type A AV means checking machine torque and the service factor for the load type, the diameter of both shafts, the rotation speed and the working environment. Dynamic balancing matters most when the coupling turns fast. At assembly, align the shafts as closely as possible before tightening, confirm the elastic element is not forced, and inspect the rubber condition and screw tightness on a regular schedule.

For a quote, provide the model or AV code, both shaft diameters, and the power and rpm of the motor and driven machine. With those details we help you select the correct size and return the quote. If you need another Type A variant, send the code or model by WhatsApp or email and we will quote it. The team replies promptly, suggests equivalents and assists with selection.
