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.
