High Damping Rubber Bearing

The high damping rubber bearing is a type of seismic isolators for buildings. This laminated composite rubber isolation bearing with high damping performance is made by adding various ingredients in the natural rubber. The high damping rubber bearing not only maintains the good mechanical properties of the natural rubber bearing, but also has a high damping ratio, which can effectively absorb the seismic energy in the earthquake and reduce the impact of the earthquake. 

Features of High Damping Rubber Bearing

  • Green and environmentally friendly;

  • No lead pollution.

Application of High Damping Rubber Bearing

This high damping rubber bearing is widely used in seismic isolation design and seismic reinforcement renovation of bridges, buildings, hydropower projects and other civil structures.
