Introduction

[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;
