Product Description

The robber absorber is a type of equipment that converts mechanical vibration kinetic energy into heat energy, which is then absorbed by the high elastic deformation properties of the rubber material.
Its core functions encompass:
Energy dissipation: It consumes vibration energy by utilizing viscous shear and elastic hysteresis effects.
Momentum isolation: It blocks the vibration transmission path, thereby reducing the risk of system resonance.
Buffer protection: It absorbs shock loads and extends the service life of the equipment.
Zhongmu Rubber is dedicated to developing both existing and new products, offering customers high-quality, high-performance isolation solutions.
