• Check the service factor appropriate to its application in the table below.

• Calculate the power to be transmitted by using the service factor, as shown below: • Choose a Vulkan Discflex coupling with transmissible power superior or equal to the calculated one.

• Check if the maximum bores of the coupling comply with the diameters of the machines’ shafts.

• Check if the DBSE (Distance Betweem Shaft Ends) is appropriate to your project.

• Check the coupling’s maximum speed and if the balancing is necessary.
