Excellent Precision
Zero backlash noticed on my CNC axis. Very rigid coupling.
Description
This diaphragm coupling connects servo motors to driven shafts for high-torque motion control applications. Constructed from aluminum alloy, it utilizes an elastic single or double diaphragm design to compensate for misalignment while maintaining torsional rigidity. The component is engineered for precision transmission in automated machinery and robotic systems. Ensure shafts are properly aligned during installation to maximize coupling lifespan and performance.
