Zero Backlash Composite Disc Couplings (CD® Couplings) from Zero-Max are designed and manufactured for applications requiring the highest performance possible. They 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 models, in a compact and maintenance-free design. The CD Coupling allows machines to maximize output and performance in demanding applications.
Composite disc flexible shaft couplings from Zero-Max are available in single-disc, double-disc, floating 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 models
Operational temperature range of -70° to 250°F (-57° to 121°C)
High torsional stiffness for high accuracy operation
Black oxide coatings on steel hubs and black anodizing on aluminum hubs for general environment protection
Longer life than metal disc models
Stainless-steel and Nickel-plated models are also available
Non-conductive and chemical-resistant disc pack material
Precision machining and tolerancing for proper fit, high concentricity, and ultimate performance
Unitized disc pack for easy installation and replacement
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 products 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 models.
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 products. 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.
Motion Control Composite Disc (CD) Couplings are ideal for Packaging Machinery and Dynamometer & Test Machinery application due to their zero backlash operation, shaft misalignment capacity, and high torsional stiffness to reliably perform in high-speed positioning applications. Composite Disc Couplings are field-proven in a large variety of applications and industries over decades of use. Specific uses include:
Packaging Machinery: These composite disc flexible shaft couplings feature zero backlash and high torsional stiffness for reliable indexing and high cycle rates.
Dynamometer & Test Machinery: Our patented composite disc pack design delivers more versatility and better performance than metal disc couplings. We engineered our CD couplings to perform in high-speed applications and to handle high levels of misalignment, while keeping reaction loads low on the connected components.
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 may have high torsional stiffness specifications; however, they can be too brittle to withstand the punishment of high-speed reversing applications, especially wheremisalignment is present.
High torsional stiffness and high dynamic load capacity, ensuring reliable machine operation
Superior shaft engagement via a clamp style hub design
Precise positioning under high speed reversing loads without fatigue for reliable 24/7 operation
Excellent chemical and moisture resistance
A unique design for superior misalignment capacity and long operational life
Maintenance-free in hostile environments
