Disc Coupling



Disc Coupling -

Clamping Screw Double Disc Type



The DC Series has the most ideal materials and structure for zero backlash and has excellent resistance to repeated stress. Since the eccentricity is small, it is necessary to accurately align the two axes. It does not require separate maintenance and has excellent oil and heat resistance.
