Product Description

The rubber absorber is an innovative device designed to transform mechanical vibration kinetic energy into heat energy. This transformation is achieved through the exceptional high elastic deformation properties of premium quality rubber material.
Its core functions encompass a diverse range of capabilities designed to enhance performance and reliability:
Energy dissipation: By leveraging the sophisticated effects of viscous shear and elastic hysteresis, it effectively consumes and dissipates vibration energy.
Momentum isolation: Expertly crafted to obstruct the vibration transmission path, it significantly reduces the risk of system resonance, ensuring smooth and stable operation.
Buffer protection: Engineered to absorb shock loads, it plays a crucial role in extending the service life of equipment, safeguarding investments in machinery.
Zhongmu Rubber stands at the forefront of innovation, committed to advancing both existing and new product lines. We offer customers cutting-edge, high-performance isolation solutions tailored to meet their specific needs.
