Product Description
The revolutionary rubber absorber is an advanced piece of equipment expertly designed to transform mechanical vibration kinetic energy into heat energy. This heat energy is then seamlessly absorbed by the rubber material's high elastic deformation properties, ensuring optimal performance and longevity.
The essential core functions it expertly delivers include:
Energy Dissipation: By harnessing the power of viscous shear and elastic hysteresis effects, it effectively consumes and dissipates vibration energy.
Momentum Isolation: It strategically blocks the vibration transmission pathways, significantly reducing the risk of system resonance and ensuring stable operations.
Buffer Protection: It proficiently absorbs shock loads, thereby extending the service life and reliability of the equipment.
Ningbo Zhongmu Rubber Products Co., Ltd is staunchly committed to innovating both our existing offerings and new product developments, providing customers with premium, high-performance isolation solutions.
