Flexible Shaft Couplings
Shaft misalignment can limit a machine’s performance, cause excessive vibration, high reaction loads, and accelerated wear, and often leads to premature equipment failure. Flexible Shaft Couplings can help prevent these issues by transmitting torque while compensating for parallel, angular, and axial misalignment between drive components. When installed correctly, flexible shaft couplings can also reduce vibration, minimize noise, and protect driveshaft components.
High-Performance Flexible Shaft Couplings from the Industry LeaderZero-Max is an industry-leading Flexible Shaft Coupling manufacturer. Our zero-backlash Flexible Shaft Couplings handle large shaft misalignments without causing high radial stress and perform better than other flexible or rigid coupling alternatives in high-performance applications. Passion and quality, along with decades of experience and expertise, went into designing each of our shaft coupling lines. The results are components that deliver:
Choosing the Right Flexible Shaft Coupling for Your ApplicationFlexible Shaft Couplings provide torque transmission while helping to improve machine performance and life, but using the wrong type of coupling can impede mechanical performance. Couplings that are too rigid can create excessive bearing loads that can impact performance and life. Couplings with backlash or that “wind-up” in applications with changing speeds can limit a machine’s operating speed and performance. Incorrect installation or using shaft couplings outside their recommended ratings can also cause issues.
Primary considerations for properly selecting a flexible shaft coupling include torque capacity, motion profile, maximum RPM, shaft sizes, and the type and amount of misalignment. Once installed, a coupling should be relatively easy to connect and disconnect for inspection, as needed.
Our Proven Designs Help You Achieve Optimal PerformanceWe offer Flexible Shaft Couplings in various models and styles, including series that are designed specifically for servo motor, automation, and wind turbine applications. You can also request custom shaft couplings engineered to meet your unique application requirements. View our catalog to learn more about all our shaft coupling options.

Composite Disc CouplingsComposite Disc shaft couplings (CD® Couplings) withstand the rigors of the most demanding servomotor systems. We manufacture the functional parts of CD shaft couplings from aerospace-grade, precision-oriented and layered composite materials. These best-in-class flexible couplings handle shaft misalignments while providing high torsional stiffness and zero backlash operation for machines with aggressive motion profiles such as repetitive reversing, stopping, indexing, and high cycle rates.
Choose from Single-Flex, Double-Flex, and Floating Shaft couplings with either clamp type or set screw hubs, depending on the model selected. A variety of materials and plating are also available. Standard CD Flexible Shaft Couplings are available for shaft sizes ranging from 0.250” to 6.00” diameters, with peak torque transmission up to over 94,000 in-lbs. Larger sizes and higher torque designs are available upon request. Zero-Max also has extensive custom capabilities for our CD Couplings.
