Product Description

The rubber absorber is an innovative piece of equipment designed to transform mechanical vibration kinetic energy into heat energy seamlessly. This transformation is magnificently achieved through the superior elastic deformation properties of the high-quality rubber material, ensuring optimal performance.
The primary functions of this remarkable product include:
Energy dissipation: It ingeniously consumes vibration energy through the utilization of viscous shear and elastic hysteresis effects, making it highly efficient.
Momentum isolation: By effectively blocking the vibration transmission path, it significantly reduces the risk of system resonance, ensuring smooth operation.
Buffer protection: It brilliantly absorbs shock loads, thereby extending the service life of the equipment and enhancing durability.
Zhongmu Rubber takes pride in its commitment to developing both existing and new products. Our goal is to provide customers with high-quality, high-performance isolation solutions you can trust.
