Dynamic balancers are devices used to reduce vibrations in rotating machinery. They work by adjusting the distribution of mass around the rotating axis, ensuring that the center of mass aligns with the axis of rotation. This helps maintain smooth operation and prolongs the life of the equipment. These balancers are commonly used in various industries, including automotive and aerospace, to enhance performance and safety. By minimizing vibrations, dynamic balancers contribute to improved efficiency and reduced wear on components, making them essential for high-speed machinery like turbines and motors.
