Take advantage of the outstanding precision and reliability with our Aluminum Diaphragm Couplings (Disc Couplings).The couplings utilize the elastic deformation of thin, high-strength Stainless Steel Diaphragms to transmit torque while compensating for shaft misalignment. No lubrication required. The all-metal construction resists wear, oil, chemicals, and aging, providing a long, trouble-free service life.
To ensure the perfect fit for your specific application, this series is available in three structural configurations: Single, Double, and Triple Diaphragm.
THREE CONFIGURATION: Available in Single (1), Double (2), and Triple (3) Diaphragm structures. This modular design allows you to choose the perfect balance between structural rigidity and misalignment compensation.
ZERO BACKLASH PRECISION: The rigid stainless steel disc design eliminates all play and elasticity in the rotational direction, ensuring precise positioning and synchronization for servo and stepper motors.


7075 ALUMINUM HUBS: Hubs are machined from aerospace-grade 7075 Aluminum Alloy, offering superior strength-to-weight ratio compared to standard aluminum, reducing load on motor bearings.
HIGH TORSIONAL STIFFNESS: Delivers excellent torque transmission efficiency with minimal wind-up, crucial for maintaining accuracy in high-speed reversing applications.
