Product Description


The shock absorber is a sophisticated piece of equipment designed to seamlessly convert mechanical vibration kinetic energy into heat energy. This transformation is brilliantly facilitated by the high elastic deformation properties inherent in the rubber material, ensuring maximum efficiency and durability.
Its core functions elegantly encompass:
Energy dissipation: Ingeniously consumes vibration energy through the utilization of viscous shear and elastic hysteresis effects, ensuring optimal performance.
Momentum isolation: Effectively blocks vibration transmission paths, significantly reducing the risk of system resonance and enhancing the overall safety and stability of operations.
Buffer protection: Expertly absorbs shock loads to substantially extend the service life of the equipment, providing unparalleled reliability and endurance.
Ningbo Zhongmu Rubber is passionately committed to the development of both existing and pioneering new products, consistently offering customers an array of high-quality, high-performance isolation solutions tailored to meet diverse needs.
