Definition -A Balancing Drum Key is a mechanical key used to secure a balancing drum to a shaft so that both rotate together. Its purpose is to transmit torque while maintaining balance and reducing axial thrust and vibration in rotating equipment. Balancing drum keys are commonly used in turbines, compressors, and high-speed rotating machinery.
