Product Description

The robust rubber absorber is an ingenious piece of equipment designed to transform mechanical vibration kinetic energy into soothing heat energy. This transformation is made possible through the remarkable high elastic deformation properties inherent in the rubber material.
Its core functions encompass a spectrum of protective and performance-enhancing attributes:
Energy dissipation: By leveraging the impressive viscous shear and elastic hysteresis effects, it adeptly consumes and mitigates vibration energy.
Momentum isolation: It effectively obstructs the vibration transmission path, significantly diminishing the risk of system resonance and ensuring smoother operation.
Buffer protection: Ingeniously designed to absorb shock loads, it plays a crucial role in extending the service life of the equipment, safeguarding your investments.
Zhongmu Rubber is passionately committed to pioneering both existing and new products, delivering superior, high-performance isolation solutions to meet diverse customer needs.
