Product detail
The Aluminium Flexible Coupling is a precision-engineered shaft connector designed to transmit torque smoothly between motor and lead screw shafts while compensating for slight misalignments.
Made from high-strength aluminum alloy (6061-T6), this coupling provides lightweight durability, corrosion resistance, and excellent torsional rigidity—making it ideal for CNC machines, 3D printers, linear modules, and servo/stepper motor drives.
Feature of Aluminium Flexible Coupling
Its spiral-cut design allows flexible angular, parallel, and axial misalignment compensation, ensuring stable rotation, low vibration, and reliable performance under continuous operation.
Application
CNC machining centers
Stepper and servo motor drives
3D printers and engraving machines
Linear motion modules and actuators
Robotics and automation systems
Packaging and electronic assembly equipment
