Product Description

Our state-of-the-art robber absorber is a pioneering piece of equipment expertly designed to transform mechanical vibration kinetic energy into heat energy. This heat is then gracefully absorbed by the high elastic deformation properties of the superior rubber material, ensuring top-notch vibration management.
Discover its core exceptional functions, expertly crafted to perfection:
Energy dissipation: By harnessing the powerful effects of viscous shear and elastic hysteresis, it efficiently consumes vibration energy for an unparalleled energy dissipation experience.
Momentum isolation: Expertly blocks the vibration transmission path, significantly reducing the risk of system resonance and ensuring a smoothly functioning system.
Buffer protection: Elegantly absorbs shock loads, effectively extending the service life of the equipment and providing robust buffer protection.
Zhongmu Rubber is passionately committed to the innovation and development of existing and new products. Our focus is on providing customers with high-quality and high-performance isolation solutions that push the boundaries of excellence.
