Selecting the Right Composite Disc Double Flex Coupling…
Clamp Style vs. Set Screw Double Flex Couplings. Which Should I Choose?Clamping hubs are the preferred method for connecting a coupling to a shaft as they offer several advantages. They can simplify installation, do not damage the shaft they are attached to, and engage the entire shaft circumference to offer more holding power. Zero-Max offers clamp style hubs with or without keyways, depending on preference and application. Clamp style double-flex CD Couplings are available in steel or aluminum. Special materials and plating are also available upon request.
Set screws are the “traditional” way of connecting a coupling to a shaft. These require a keyway on the shaft and in the hub, so a key can be used to transmit power. Set-Screw style double-flex CD Couplings are available in steel and both special materials and plating are also available upon request.
Zero-Max also offers a series of QD (quick disconnect) bushing style hubs that allow for quick and easy mounting of a double-flex CD Coupling with use of a standard QD bushing (sold separately). Additionally, any of our double-flex Composite Disc Coupling hubs can be customized for your application and performance requirements. This includes use of shrink discs, integrated clamping hubs, flange mount hubs, and more.
Benefits of Steel vs. Aluminum CD CouplingsWhen deciding between steel or aluminum, material choice comes down to preference and the application’s requirements for strength, weight, inertia, etc. Steel is the most used material as it exhibits higher strength and density than aluminum. All our steel CD Couplings have a black oxide coating, standard. Aluminum CD Couplings are significantly lower in weight than the same size steel coupling and offer better corrosion resistance. These characteristics are ideal for wet and washdown operating environments, or servo motor applications requiring a lightweight, low inertia solution. All our aluminum CD Couplings have a black anodized coating, standard.
What About Custom Double Flex CD Couplings?Some users have specific requirements for bore diameter, torque capacity, torsional stiffness, misalignment capacity, mounting, and other factors. If you do not find a stock option that meets your specifications, we offer custom-tailored double disc CD Couplings to meet your application and performance needs.
