Disc Coupling



Disc Coupling -

Clamping Screw Single Disc Type



The DC-SA Type is a single disc plate type. It is suitable for small spaces because it is short. Since the disc flow rate is relatively smaller than that of the double disc type, the two axes must be well aligned. The surface is hard anodized, so it has excellent corrosion resistance, oil resistance, and chemical resistance.
