These highly resilient shaft couplings consist of the 'Giubo coupling ring', a resilient element made of natural rubber, and two steel flanges between which the resilient ring is clamped. Depending on the size of coupling, four, six or eight spacer sleeves, which take the connecting bolts, are vulcanised into the fixing points of the coupling ring. The couplings which are resilient in the direction of rotation, can run at an angle and will allow both axial and radial displacement. They are thus the ideal connecting element for all drives which are running uneven, prone to shock loading, and in which damaging peak torques or rotary vibrations have to be smoothed out; the choice of various 'Shore hardness grades' for the 'Giubo ring' allows for different damping characteristics.

In normal cases the high resilience coupling ring consists of natural rubber with a hardness of 65 Shore A; this operates reliably in the range between -25 °C and 70 °C. As well as its widespread use as a flexible element in drive trains, it can be used as a resilient cardan shaft and can also be used in conjunction with dry-running clutches.
