High-Strength Disc Coupling
High-Strength Disc Coupling -
Clamping Screw Single Disc Type
HDC-SA Type is a high-strength single disc structure. It is suitable for small spaces because it is short in length. Since the disc has little fluidity, the two axes must be particularly well aligned. The hub is made of high-strength duralumin (AL 7075-6T) and the surface is anodized to provide excellent corrosion resistance, oil resistance, and chemical resistance.
