iHF High-Sensitivity Diaphragm Coupling Servo Stepper Motor Elastic Coupling
Productfeatures:
The Screw Clamping Type High-Sensitivity Diaphragm Coupling features a high-strength aluminum alloy hub and a 304 stainless steel diaphragm. It provides high torsional rigidity and a zero-backlash connection for precise motion control, with low inertia for excellent high-speed response and symmetrical bidirectional performance.
Specifically optimized for servo and stepper motors, its design effectively compensates for angular and axial misalignment. It is ideally suited for demanding applications including industrial robot joints, CNC spindles, precision automation equipment, and medical/optical instruments, ensuring reliable, accurate, and durable power transmission.
