1.The use of excellent stainless steel as elastic material coupling with high torsional,rigidity ,moresuitable for automatic control drive rapid response .

 2.No backlash ,hysteresis can be high precision repeat positioning.

 3.Low inertia dsign ,for positive and negative operation ,braking etc,can fully play its excellent durability.

 4.The coupling most suitable for the feed shaft spidle of NC machine.
