Product Highlights
- Lead core energy dissipation and seismic isolation with stable vertical bearing capacity, consume seismic energy and protect building structures.
- Solve poor shock resistance, large displacement and structural damage of ordinary bearings. Self-energy dissipation and reset reduce vibration and deformation.
- High damping coefficient and excellent energy consumption, strong bearing capacity and high reset accuracy, anti-aging and anti-fatigue with stable long-term performance.
- Suitable for bridges, viaducts and buildings in high seismic intensity areas, improve seismic grade and reduce post-disaster maintenance costs.
- Better seismic energy dissipation and automatic reset function, higher stability than ordinary rubber bearings, more suitable for severe seismic working conditions.

Product Description
Product Description
High Damping Rubber Bearing – Fixed and Sliding Types for Large Displacement
High damping rubber bearing, also called HDR bearing pad, is one of seismic isolation bearing. It has excellent seismic isolation performance to effectively reduce the bridge damage caused by earthquake.
HDR bearing pad is composed of specialized designed rubber with high damping performance, sandwiched together with steel plate layer. When installing, the high damping rubber bearing is commonly used with top and bottom steel plate and connection accessories.
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.
Joint structure
*The HDR (Ⅰ) rubber bearing. It is designed with top and bottom embedded steel plate. And the rubber bearing is connected with pier and beam by sleeve. The top and bottom loading plate is connected with sleeve by anchor bolt. The top and bottom embedded steel plate is connected with sleeve by welding.
*HDR (Ⅱ) rubber bearing. It is designed with top embedded steel plate and without bottom embedded steel plate. The bottom loading bearing is connected with sleeves with anchor bolts. The top embedded steel plate is connected with top loading plate with shear tenon. And the top embedded steel plate is connected with sleeve by welding.
*HDR (Ⅱ) rubber bearing. It is designed with top embedded steel plate and without bottom embedded steel plate. The bottom loading bearing is connected with sleeves with anchor bolts. The top embedded steel plate is connected with top loading plate with shear tenon. And the top embedded steel plate is connected with sleeve by welding.

FAQ
Q1: What is a high damping bridge bearing?
A: It is a laminated rubber bearing made with a high damping compound that also absorbs quake energy.
A: It is a laminated rubber bearing made with a high damping compound that also absorbs quake energy.
Q2: How does it differ from a plain laminated bearing?
A: The compound gives a higher damping ratio, so the bearing dissipates energy as well as carrying load.
A: The compound gives a higher damping ratio, so the bearing dissipates energy as well as carrying load.
Q3: Does it need a separate damper?
A: No -- load carrying, restoring force, and damping sit in one unit.
A: No -- load carrying, restoring force, and damping sit in one unit.
Q4: Is a lead core used?
A: No -- the HDR type damps through its rubber compound, without a lead plug inside the body.
