Disc coupling

- Large shaft hole containment diaphragm coupling, high speed diaphragm coupling, high performance diaphragm coupling, good dynamic balance repeatability;

- Easy installation, simple disassembly, suitable for large fans, pump sets, high speed units;

-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 Bnk Technology;

- For units with thermal expansion, the cold pre-tension should be taken into account during installation to allow the flexible element to work in a small deformation zone and increase the service life;
