Motion system designers have a new option to arrest electrical current. In addition to their primary function, Zero-Max CD couplings are designed with composite flex elements that are non-conductive.
The flex element designed into Zero-Max CD couplings provides electrical insulation while protecting mechanical components from system overloads. CD Couplings do not pass electrical current through the coupling.
In addition to protecting from stray electrical current, CD couplings protect generators in a system from transferring lower reaction loads to the generator bearings. The coupling’s composite discs withstand all types of environmental elements, including temperature extremes from -40 to +70°C, and also moisture and chemicals.
Additional operating features include: zero backlash, excellent for reversing loads, smooth operation at high speeds, and compact size with a clamping system that fits most applications. CD couplings have very long life cycles and require less replacement over time. They provide exceptional cost-effectiveness and reduced waste.
CD couplings are available in many models and sizes, including custom designs for unusually large and challenging applications such as wind turbines. Standard models and sizes include single and double flex models with clamp style hubs with or without keyways. The torque capacities range from 40Nm to 1436Nm and beyond with speed ratings from 4400 RPM to 17,000 RPM.
