GUMMI VND 400 semi-flexible coupling

GUMMI VND 400 belongs to semi-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 VND 400 and any equivalents.

The Gummi VND jaw semi-elastic coupling connects two shafts using an elastic element and a steel ring, and includes an additional hub. It transmits torque from a motor to a driven machine while accommodating misalignment and reducing vibration. MR Industrial Accessories LLC supplies this coupling and quotes it by part number through WhatsApp or email.

The VND series belongs to the Gummi line of jaw semi-elastic couplings. Its design uses an elastic element placed between the jaws of the hubs, held in place by a steel ring. While the VN configuration joins a jaw hub and a ring-carrier hub, the VND version adds a third hub. The model code combines the series letters with a size number, such as VND 170, VND 200 or VND 240.

These couplings are found in equipment that requires torque transmission between shafts that may not be perfectly aligned, and where damping of load fluctuations is beneficial. Typical applications include pumps, fans, conveyor belts, mills, mixers and other process machinery. They are often used on drives where an electric motor or gearbox starts and stops frequently.

When selecting a VND size, refer to the maximum torque, maximum allowable speed and outer diameter listed for each model. The actual torque demand is adjusted by a service factor that depends on the load type and daily operating hours. Shaft diameters and alignment also matter: proper alignment helps extend the life of the elastic element. Maintenance involves inspecting the elastomer and the steel ring for wear.

To request a quote, provide the model or part number (for example VND 170, VND 200 or VND 240), the diameters of both shafts, and the power and rpm of the motor and driven machine. With these details, the team can help you choose the correct size and suggest equivalents if needed. For other variants in the line, send the part number or model via WhatsApp or email.
