    [BF disc coupling]

    Quick installation coupling,High speed coupling
    Large shaft hole containment diaphragm coupling, easy to install, easy to disassemble, good dynamic balance performance, suitable for high speed units;

    Disc coupling

    -Other special structures can be designed according to customer requirements;

    -Coupling material can be selected according to customer requirements;

    -The dimensions in the figure can be made according to customer requirements; other technical parameters can be consulted by Bunker Technology Department;

    -For units with thermal expansion, the cold pre-tension should be considered during installation to make the flexible components work in a small deformation interval and improve the service life;
