What role do rubber vibration isolators play in industrial applications?
Rubber vibration isolators use the elastic properties of rubber to reduce mechanical vibration, shock, and noise. They absorb and reflect vibration energy, preventing the propagation of vibration waves, thereby achieving damping, noise reduction, and minimizing impact-related damage.
