    Saga is a general purpose, torsionally soft coupling with high tolerance to all forms of misalignment. The design features hexagonal or octagonal rubber donut-shaped elements with metal inserts positioned at each apex during the vulcanization process. These metal inserts carry actual bolts which fix the element to tines on cast, cylindrical hubs. Embedded inserts also have tines which connect with mating surfaces on hubs so that axial bolts can be easily torqued during assembly without twisting the rubber beyond the limits of its elasticity. The rubber between each apex is pre-compressed, so it is much more durable to the stresses arising from the various forms of misalignment and torsional vibrations.
    Note: A complete Saga coupling is comprised of 2 hubs, an elastomeric donut, and hardware.
