Composite Disc Floating Shaft Couplings

Floating shaft couplings, also called spacer couplings, are designed for applications where drive and load components are spaced far apart from each other. These zero-backlash and torsionally stiff solutions from Zero-Max provide superior misalignment capacity and can be made to any length requirement.
Composite disc couplings (CD® Couplings) from Zero-Max provide very low reaction loads and are excellent for reversing applications. Select from a wide range of floating shaft CD couplings in aluminum, steel, and stainless steel, with clamp-style or set-screw hubs.

- Clamp-Style hub floating shaft couplings are the preferred method for connecting the coupling hub to the shaft as they engage the shaft’s entire circumference. This hub style offers more holding power, is typically easier to install, and will not damage the shafts. Clamp type CD Coupling hubs from Zero-Max are available with keyways or without keyways, depending on preference and application.
- Set-Screw hub floating shaft couplings require a keyway on the shaft and in the coupling, so a key can be used to transmit power. This “traditional” way of connecting couplings to shafts offers good holding power and easy installation.
The Best Solution for Widely Spaced Drive Components
For long spans between motion components, Zero-Max floating shaft spacer couplings are the answer you need. Our CD couplings have superior misalignment capacity, help minimize radial loads on the connected equipment, and provide excellent support for connected components.High torsional stiffness and zero backlash operation make these drive shaft couplings ideal for high performance and demanding applications. Precision machining and precision hardware ensure smooth and accurate operation, even at high speeds and lengths.
Floating shaft CD Couplings come with set screw hubs or clamp type hubs. Additional features and benefits include:
- Zero backlash performance
- High torsional stiffness
- Excellent for reversing loads
- High shaft misalignment capacity
- Very low reaction loads on connected equipment and bearings
- Customizable to the exact length requirements
- Clamp type hubs are available with or without a keyway
Dynamic Balancing and Close Tolerances
The close tolerances at which we manufacture our composite disc floating shaft couplings, along with the patented composite disc pack, make these devices well-suited to high speed and/or long-span applications. Some applications, however, may require dynamic balancing of the floating shaft coupling for optimal performance. Our designers will work with you to determine whether this is necessary for your specific application.Smooth Operation and Reduced Misalignment
In most cases, our composite disc floating shaft couplings’ misalignment capacity is related to the speed at which they operate and the mass of the floating shaft (governed by its diameter and length). By reducing the allowable misalignment, and therefore the stress on the disc, the disc pack can better support and stabilize the floating shaft. This ultimately results in smoother operation, less vibration of the connected equipment, and longer operational life. Contact our support team for further details.
