Product Description

The rubber absorber is an innovative piece of equipment that adeptly transforms mechanical vibration kinetic energy into heat energy. This heat is seamlessly absorbed by the rubber material, thanks to its remarkable high elastic deformation properties.
Its core functionalities include a trio of pivotal benefits:
Energy Dissipation: This marvel absorbs vibration energy by ingeniously utilizing viscous shear and elastic hysteresis effects, ensuring optimal energy management.
Momentum Isolation: By blocking the vibration transmission path, it effectively reduces the risk of system resonance, maintaining system integrity.
Buffer Protection: It adeptly absorbs shock loads, thereby significantly extending the service life of your equipment, safeguarding it from wear and tear.
Zhongmu Rubber is steadfast in its commitment to the development of both existing and groundbreaking products, providing customers with high-quality, high-performance isolation solutions that stand the test of time.
