Product Description

Discover a revolutionary component in the world of vibration management: the rubber absorber. This ingenious equipment transforms the kinetic energy from mechanical vibrations into heat energy, which is effortlessly absorbed by the exceptional elastic deformation properties of the finest rubber material.
Its core functions encompass a trifecta of superior performance indicators:
Energy Dissipation: Experience unparalleled energy consumption of vibration through the sophisticated use of viscous shear and elastic hysteresis effects, ensuring a smoother, quieter operation.
Momentum Isolation: Ingeniously blocks the transmission path of vibration, significantly minimizing the risk of system resonance for a more reliable and stable performance.
Buffer Protection: Expertly absorbs shock loads, thereby extending the service life of your equipment, ensuring durability and sustained operational excellence.
At Zhongmu Rubber, we are relentlessly committed to the pursuit of innovation. We strive to enhance both our existing and groundbreaking new products, delivering high-quality, high-performance isolation solutions that exceed customer expectations.
