Product Description

Product Description

The high-damping bearing is an advanced support device designed for bridges, buildings, and other engineering projects. By utilizing high-damping materials, it effectively reduces structural vibrations and dynamic loads, enhancing overall seismic performance and user comfort. This bearing is widely used in high-rise buildings, bridges, tunnels, and other applications requiring vibration reduction.

Working principle

During earthquake, the vibration from various directions will impact fixed base building and results in deformation and building or bridge damages. The high damping bearing pad is improved through high damping material, which the damping ratio can approach to 15% to 18%.

When the earthquake comes, the high damping rubber bearing will increase the horizontal displacement through rubber shear deformation and reduce friction coefficient. The large displacement can weaken the vibration from all direction and reduce the damage of building and bridges.

Feature

1.Superior Vibration Damping: The high-damping design effectively absorbs and dissipates vibrational energy, significantly reducing the impact of dynamic loads on structures.

2.High Load-Bearing Capacity: Precisely engineered to support larger loads, making it suitable for heavy-duty applications.

3.Durability: Made from high-quality materials, it exhibits excellent aging resistance and corrosion resistance, suitable for various environmental conditions.

4.Flexibility and Adaptability: The bearing can accommodate structural deformations while maintaining stable support performance, helping to extend the lifespan of the structure.
