A wind turbine coupling must be able to withstand extreme winds and adverse, ever-changing climate conditions to maintain high levels of performance and avoid costly turbine downtime.  With that in mind, Zero-Max has developed an advanced, all-in-one disc coupling solution for many wind turbine drivetrains.
Our Flexible Composite Disc Couplings and Torque Limiters continue to be a preferred source for many new turbine installations as well as after-market upgrades/replacements.  The unique design of the patented composite disc-packs used in Zero-Max wind turbine couplings allows for maximize performance and field-proven reliability.  Zero-Max Couplings are designed and engineered to exceed the typical operational life of standard driveline couplings.


Patented, Proven Disc Coupling Design

Zero-Max’s flexible composite disc wind turbine couplings feature a unique, patented composite disc design that can withstand harsh environmental conditions.  
Our flexible, dielectric composite disc couplings provide electrical isolation to nullify current leaks from the generator into the gearbox, helping to prevent damage to bearings and teeth. Zero-Max’s intelligent design minimizes reaction loads while providing the required torsional stiffness value to suit these demanding drivetrain requirements.
The composite materials used in our wind turbine disc couplings are designed and tested to withstand a wide range of environmental conditions, including moisture, chemicals, and extreme temperatures from -57° to 121°C (-71° to 250°F).  Used in conjunction with our wind turbine torque limiters, our composite disc couplings provide the highest level of overall protection for modern wind turbine drivetrain requirements.
