Introduction
[BG disc coupling]
Quick installation coupling,High speed couplingDisc 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;
