Product Description

The rubber absorber stands as a pivotal equipment designed to transform mechanical vibration kinetic energy into heat energy. This transformation is adeptly managed through the remarkable high elastic deformation properties of the rubber material, ensuring efficient energy absorption.
The core functionalities of this innovative absorber include:
Energy dissipation: By leveraging the viscous shear and elastic hysteresis effects, it proficiently consumes vibration energy.
Momentum isolation: It significantly disrupts the vibration transmission pathway, thereby mitigating the risk of system resonance and enhancing system stability.
Buffer protection: Expertly designed to absorb shock loads, this feature notably extends the service life of equipment by providing robust protection.
Zhongmu Rubber is passionately committed to advancing both its current product offerings and pioneering new innovations, delivering high-quality, high-performance isolation solutions that empower customers with superior results.
