High Damping Rubber Bearing

The high damping bearings are laminated composite rubber isolation bearings with high-damping performance made by adding various ingredients to natural rubber. These high damping bearings not only maintain the good mechanical properties of natural rubber bearings but also have a high damping ratio, which can effectively absorb seismic energy during an earthquake and reduce its impact.

Features of High Damping Rubber Bearing

  • Green and environmentally friendly;

  • No lead pollution.



Application of High Damping Rubber Bearing

The high damping rubber bearing, a type of high damping bearing, is an effective seismic isolators for buildings. It is widely used in seismic isolation design and the seismic reinforcement and renovation of bridges, buildings, hydropower projects, and other civil structures.
