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, zero-backlash couplings can reduce vibration, minimize noise, and protect drive shaft components.

High-Performance Flexible Shaft Couplings from the Industry Leader

Zero-Max is an industry-leading 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 alternatives in high-performance applications. Passion, quality, service, and decades of experience and expertise went into designing each of our lines. The results are components that deliver:
  • Zero Backlash operation
  • Exceptional performance and precision
  • Perfect for high-speed applications
  • High torsional stiffness
  • Low reaction loads
  • No lubrication required
  • Maintenance-free
  • Long operational life

Choosing the Right Flexible Shaft Coupling for Your Application

Flexible Shaft Couplings provide torque transmission while helping to improve machine performance and life, but using a low performance coupling or the wrong type of coupling can impede mechanical performance. Products that are too rigid can create excessive bearing loads that can impact performance and life. 

Options with backlash or that “wind-up” in applications with changing speeds and/or direction can limit a machine’s operating speed and performance. Incorrect installation or usage outside their recommended ratings can also cause issues. 
Primary considerations for selecting a flexible shaft coupling include torque capacity, torsional stiffness, motion profile, maximum RPM, shaft sizes, and the type and amount of misalignment. Once installed, maintenance free operation is important as is the ability to connect and disconnect for inspection, as needed, relatively easy.

Our Proven Designs Help You Achieve Optimal Performance

We offer Flexible Shaft Couplings in various models and styles, including a series specifically designed for servo motor, automation, and wind turbine applications. You can also request custom designs engineered to meet your unique application requirements. View our catalog.

Composite Disc Couplings

Precision CD® Couplings are engineered and built to withstand the rigors of the most demanding servomotor systems. High torsional stiffness and zero backlash operations deliver repetitive reversing, stopping, indexing, and high cycle rates. Available CD® Coupling models include:

ServoClass® Shaft Couplings

These zero-backlash precision metal disc-style couplings offer high torsional stiffness and superior misalignment capacity while helping to reduce reaction loads on connected components. 

Control-Flex Shaft Couplings

These zero backlash flexible shaft couplings are engineered to ensure accuracy and feature clamp hubs for a superior, secure, and vibration-resistant shaft connection. The Control-Flex Shaft Couplings' flex elements offer ultralow bearing reaction loads caused by shaft misalignments. 

Schmidt Couplings

This line includes models for large shaft offsets or inline shaft applications with smaller shaft offsets. Schmidt Couplings are uniquely designed to handle applications with challenging misalignment issues or large fixed or variable shaft offsets.
