This catalogue of couplings covers a comprehensive range of mechanical components designed to connect rotating shafts and transmit torque steadily across various mechanical systems. As core transmission parts, couplings effectively compensate for common shaft misalignment, including angular, parallel and axial deviations, while absorbing operational vibration and impact loads to protect mechanical equipment from premature wear and structural damage. The catalogued couplings are broadly categorized into rigid and flexible types with distinct functional characteristics. Rigid couplings ensure precise and stable shaft connection for high-precision operating scenarios with accurate shaft alignment. Flexible couplings adopt elastic or movable structures to adapt to complex operating conditions, delivering better buffering and misalignment tolerance. All listed couplings comply with universal mechanical industry standards, adapting to diverse industrial scenarios such as power equipment, transmission devices and automated machinery to guarantee stable, efficient and long-term system operation.
