Product Description


The robust shock absorber is a state-of-the-art engineering marvel, skillfully transforming mechanical vibration kinetic energy into beneficial heat energy. This energy is then expertly absorbed by the superior high elastic deformation properties of our specially-engineered rubber material.
Its core functions boast a range of impressive capabilities:
Energy dissipation: Ingeniously consuming vibration energy through the exceptional viscous shear and elastic hysteresis effects.
Momentum isolation: Masterfully obstructing the vibration transmission path, thereby significantly diminishing the risk of system resonance-related issues.
Buffer protection: Profoundly absorbing shock loads to extend the equipment’s operational life span.
Zhongmu Rubber is passionately committed to the innovation and development of both current and groundbreaking products, providing customers with unparalleled high-quality, high-performance vibration isolation solutions.
