Features 2. Used as damping elements for vibration and noise control. 1. Mainly used for air compressors, diesel engines, gasoline engines, water pumps. 3. Protect the machine's normal work and get good surroundings, reducing noise and shock obviously. 5. In audio equipment and instruments, avoid machine vibration interference, having a good buffer. 4. Simple geometrical design supports dynamic performance and stability under lateral/sideways forces. Features: 1. Mainly used for air compressors, diesel engines, gasoline engines, water pumps. 2.
