Product Description

The revolutionary robber absorber is an advanced piece of equipment designed to transform mechanical vibration kinetic energy into heat energy. This heat is then seamlessly absorbed, thanks to the remarkable high elastic deformation properties of the specially engineered rubber material.
Its core functions encompass a suite of sophisticated capabilities:
Energy dissipation: It skillfully consumes vibration energy by harnessing the power of viscous shear and elastic hysteresis effects, ensuring optimal performance.
Momentum isolation: This function adeptly obstructs the vibration transmission path, significantly diminishing the risk of system resonance, thereby safeguarding your equipment.
Buffer protection: Expertly absorbs shock loads, this feature plays a crucial role in dramatically extending the service life of your equipment.
Zhongmu Rubber is committed to the relentless development of both existing and groundbreaking new products. We proudly offer customers high-quality, high-performance isolation solutions that set the standard in the industry.
