Product Description

The rubber absorber is an innovative piece of equipment that ingeniously transforms mechanical vibration kinetic energy into heat energy. This energy is gracefully absorbed by the rubber's exceptional high elastic deformation properties, making it a pivotal component in the reduction of mechanical noise and vibration.
Its core functions encompass a variety of transformative capabilities that ensure optimal performance and durability:
Energy dissipation: The rubber absorber skillfully consumes vibration energy by leveraging the effects of viscous shear and elastic hysteresis, thus safeguarding the structure's integrity.
Momentum isolation: This feature adeptly disrupts the vibration transmission path, significantly diminishing the risk of system resonance and enhancing operational stability.
Buffer protection: Through its ability to absorb shock loads, it substantially extends the service life of equipment, providing a robust buffer against mechanical stress.
Zhongmu Rubber is passionately committed to advancing both existing products and pioneering new solutions, to furnish our customers with high-quality, high-performance isolation solutions that stand the test of time.
