Product Description

The rubber absorber is an innovative piece of equipment designed to transform mechanical vibration kinetic energy into heat energy. This incredible process is facilitated by the high elastic deformation properties inherent in the rubber material, effectively absorbing and reducing unwanted vibrations.
Its core functions encompass a variety of essential capabilities:
Energy dissipation: Through the strategic use of viscous shear and elastic hysteresis effects, it proficiently consumes and dissipates vibration energy, safeguarding your equipment from potential damage.
Momentum isolation: By effectively blocking the vibration transmission path, it significantly reduces the risk of system resonance, ensuring smoother and more reliable operations.
Buffer protection: It adeptly absorbs shock loads, providing invaluable buffer protection that extends the service life of equipment, maintaining high performance over time.
Zhongmu Rubber is unwavering in its commitment to innovating and enhancing both existing and new products. Our goal is to offer customers unrivaled high-quality, high-performance isolation solutions that meet the demands of various applications.
