Streamline your mechanical assembly with the Aluminum Diaphragm Coupling with Flange. Unlike standard couplings that connect two shafts, this specialized model features a Flange Interface on one or both sides, allowing for direct mounting to robotic arms, indexing tables, flywheels, or custom fixture plates. It effectively compensates for axial, radial, and angular misalignment while maintaining high torsional stiffness.
Ideal for high-precision automation equipment where space is limited and direct face-mounting is required, such as in textile machinery, medical scanning devices, and precision printing systems.
ZERO BACKLASH: The stainless steel disc pack ensures immediate torque transmission with no play, crucial for maintaining positioning accuracy in servo-driven applications.
HIGH TORSIONAL STIFFNESS: Provides a rigid connection that resists twisting under load, ensuring precise synchronization between the drive motor and the load.


LIGHTWEIGHT ALUMINUM CONSTRUCTION: Made from premium aluminum alloy to minimize rotating mass and inertia, allowing for higher acceleration rates in dynamic systems.
MISALIGNMENT COMPENSATION: The flexible metal diaphragm absorbs unavoidable shaft misalignments (angular, radial, axial), protecting bearings and extending system life.
