Product Description

The rubber absorber is an innovative type of equipment designed to ingeniously transform mechanical vibration kinetic energy into heat energy. This energy is then expertly absorbed by leveraging the superior elastic deformation properties inherent in the high-quality rubber material.
Its core functions encompass a range of sophisticated capabilities:
Energy dissipation: This function masterfully consumes vibration energy by utilizing advanced viscous shear and elastic hysteresis effects, ensuring optimal performance.
Momentum isolation: It acts as a formidable barrier, effectively blocking the vibration transmission path, thereby significantly reducing the risk of system resonance.
Buffer protection: It adeptly absorbs shock loads, thereby playing a crucial role in extending the service life of your valuable equipment.
Zhongmu Rubber is passionately committed to the continuous development of both existing and pioneering new products, providing customers with high-quality, high-performance isolation solutions that excel in reliability and efficiency.
