Disc Coupling

Disc Coupling -

Clamping Screw Double Disc Type



The DC Series is a coupling that bolts together a highly elastic metal disk between the hub and the hub that fixes the shaft. Since all materials are made of metal, it can be applied to places where there is a lot of heat generation. The DC-A Type has a large disk diameter compared to the shaft diameter, so it can be selected with a high commercial torque.
