High Damping Rubber Bearing

The high damping bearings from Tiantie Group 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

  • the high damping rubber is green and environmentally friendly;

  • No lead pollution of the high damping bearings ensures compliance with health and safety standards.



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.
