High-Strength Disc Coupling

High-Strength Disc Coupling -

Clamping Screw Double Disc Type



The HDC Series is a coupling that secures the shaft and has a strong elastic metal disk between the hub and the hub, which is strongly assembled with several bolts. Since all materials are made of metal, it can be applied to places where there is a lot of heat generation. The HDC-A Type can be selected with a high commercial torque because the disk diameter is large.
