Annular elements have high torsional and radial flexibility, combining axial and angular flexibility. The design has sufficient secondary inertia size. With high torsional flexibility and variable adaptability of the first end, individual torsional requirements can be met by using different degrees of Shore hardness. Damping torsional vibration and shock, and compensating for considerable axial, radial and angular misalignments. Efficient ventilation allows high energy loss.

* Small installation workload. Optional fail-safe device. acc is connected to the flywheel
