Floating shaft couplings, also called spacer couplings, are designed for applications where drive and load components are spaced far apart. Zero-Max's zero-backlash and torsionally stiff solutions provide superior misalignment capacity, minimize reaction loads on connected equipment, and can be made to any length requirement.

Composite Disc Floating Shaft Couplings for High-Performance Applications
High torsional stiffness and zero backlash operation make Composite Disc drive shaft couplings ideal for high performance and demanding applications. Precision machining and hardware ensure smooth and accurate operation, even at high speeds and long lengths.Composite Disc Floating Shaft Coupling Options
Composite disc couplings (CD® Couplings) from Zero-Max provide high shaft misalignment capacity, very low reaction loads, zero-backlash performance, 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 Hubs
Composite Disc Couplings with Clamp-Style Hubs 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 Hubs
Floating Shaft CD Couplings with Set-Screw Hubs 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.Choose a category below to view available models and specifications.

Dynamic Balancing and Close Tolerances
The close tolerances at which we manufacture our composite disc floating shaft couplings and the patented composite disc pack make these devices well-suited to high-speed and 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 application. Zero-Max has in-house dynamic balancing capabilities for most applications which require this.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). The disc pack can better support and stabilize the floating shaft and, therefore, the stress on the disc. This ultimately results in smoother operation, less vibration of the connected equipment, and longer operational life.
