Providing superior misalignment capacity, Floating Shaft CD Couplings can often be a zero-backlash alternative to Cardan Shafts. The unique flex element made of composite material makes it possible to have zero-backlash, high torsional stiffness and very low bearing loads all at the same time. This is because the composite material is designed to be flexible in one plane and stiff in another plane. Composite material is not prone to fatigue and will perform much longer than stainless steel.

Custom designs are available with torque ranges from 270 inch lbs. (30 Nm) to 550,000 inch lbs. (63,000 Nm) and with speed ranges from 500 rpm to 15,000 rpm. They are available in custom lengths from 46 inches to 196 inches and with outside hub diameters of 2.25 to 12 inches.
 
Depending on the application, a wide range of spacer materials in various thicknesses are available for these couplings including 7075 aluminum, 4340 steel, stainless steel and titanium. In addition, floating shaft couplings may be specified with custom finishes such as nickel plating, black oxide and others. Hub options include clamp style hubs, conventional hubs, as well as custom hub designs.
