Zero Backlash Composite Disc Couplings (CD® Couplings) from Zero-Max are designed and manufactured for applications requiring the highest performance possible. Composite Disc Couplings are constructed to perform under the most demanding operating conditions involving repetitive speed changes, stopping, reversing, indexing, and misalignment, without sacrificing performance.

Zero-Max created the patented composite disc pack to provide the versatility and performance needed above and beyond metal disc coupling’s abilities. Our CD Couplings accommodate high speeds, large shaft misalignment, and eliminate fatigue and fretting often seen in metal disc couplings, in a compact and maintenance-free design. The CD Coupling allows machines to maximize output and performance in demanding applications.


High Speed Flexible Coupling Advantages

Composite disc flexible shaft couplings from Zero-Max are available in single-discdouble-discfloating shaft, and custom models, all engineered for the most demanding motion control and power transmission applications. Our advanced design provides the following benefits:
  • 3-times the angular misalignment of most metal disc couplings
  • High torsional stiffness for high accuracy operation
  • Longer life than metal disc couplings
  • Non-conductive and chemical-resistant disc pack material
  • Unitized disc pack for easy installation and replacement
  • Operational temperature range of -70° to 250°F (-57° to 121°C)
  • Black oxide coatings on steel hubs and black anodizing on aluminum hubs for general environment protection
  • Stainless-steel and Nickel-plated models are also available
  • Precision machining and tolerancing for proper fit, high concentricity, and ultimate performance
  • RoHS compliant

Differentiating High Speed Composite Disc Couplings from Standard Metal Disc Couplings

Metal disc couplings, which can be effective for general applications, are not designed to handle the large degrees of misalignment in many applications. They are also subject to fatigue and fretting in high demanding motion profiles that require repetitive stopping, reversing, and indexing. Under these most strenuous operating conditions, you need a coupling that delivers high performance and durability.

High Speed Flexible Coupling Options

Single-Flex Composite Disc Couplings

Single-flex Composite Disc Couplings provide the highest torsional-stiffness, and accommodate high angular misalignment and limited parallel misalignment. These couplings provide an effective and compact solution in applications where most alternatives would require a double-flex coupling. 

Double-Flex Composite Disc Couplings

Double-flex Composite Disc Couplings have a longer overall length to accommodate very high angular and parallel misalignment, providing double the misalignment capacity of some metal disc couplings.

Floating Shaft Composite Disc Couplings

Floating Shaft Composite Disc Couplings accommodate misalignment in shafts positioned a more considerable distance apart, making them ideal for coupling large spans between motion components.

Custom Composite Disc Couplings

Zero-Max custom CD Couplings are built to accommodate your unique high speeds and large shaft misalignment specifications while eliminating fatigue and fretting often seen in standard metallic disc couplings. You get the benefit of zero backlash operation, high torsional stiffness, and maintenance-free operation in a custom, compact design.

Learn how we developed a customized CD Coupling to help a customer requiring extra parallel misalignment capacity in a restricted space.

Zero-Backlash CD Couplings for High Performance Applications

High-speed Composite Disc Couplings from Zero-Max tackle your most demanding application and misalignment challenges. We can also design and manufacture a custom flexible shaft coupling to handle your unique application and performance specifications.
 
Zero-Max CD Couplings are ideal for high precision applications, including packaging machines, pick and place systems, printing machinery, Dynamometer test systems, die-cut and anvil roll processes, machine tools, commercial baking applications and most systems using servo motors that require high performance and/or to address shaft misalignment. Our high torsional stiffness, zero-backlash, maintenance-free Composite Disc Couplings are field-proven in a large variety of applications and industries over decades of use.
 

Innovative Composite High Speed Coupling Technology

Our next-generation Composite Disc Couplings allow users to transmit high horsepower in a small envelope. These high-speed flexible shaft couplings are ideal for cyclic applications where speed and repeatable accuracy are critical for keeping systems going 24 hours a day, 7 days a week.

The RoHS-compliant design is rugged enough to withstand the punishment and stress of servomotor applications. Other brands of couplings may have high torsional stiffness specifications; however, they can be too brittle to withstand the punishment of high-speed reversing applications, especially where misalignment is present.
 
  • High torsional stiffness and high dynamic load capacity, ensuring reliable machine operation
  • Precise positioning under high speed reversing loads without fatigue for reliable 24/7 operation
  • A unique design for superior misalignment capacity and long operational life
  • Superior shaft engagement via a clamp style hub design 
  • Excellent chemical and moisture resistance
  • Maintenance-free in hostile environments
