Floating Shaft CD® Couplings are a torsionally stiff, no backlash option for connecting long distances between shaft ends. They can often be a zero-backlash alternative to Cardan Shafts. The flex element made of composite material makes it possible to have zero-backlash, high torsional stiffness and low bearing loads simultaneously.
The composite material is flexible in one plane and stiff in another plane. It is not prone to fatigue and will perform longer than stainless steel. Custom designs are available with torque ranges from 270 in.-lbs (30 Nm) to 550,000 in.-lbs (63,000 Nm) and with speed ranges from 500 rpm to 15,000 rpm. They are available in custom lengths from 46 in. to 196 in. and with outside hub diameters of 2.25 to 12 in.
