Product Description

HDR High Damping Seismic Isolating Rubber Bearing 

This super high damping rubber bearing HDR-S is made of a rubber compound with high natural rubber (NR) content and has been specially designed to combine friction damping and viscous damping. As a result, it offers excellent functionality as a seismic isolation bearing, providing restorative attributes of rubber springs along with superior damping performance and high-level durability.

Features of Super High Damping Rubber Bearings

1.Environmentally friendly 
The special rubber used has a strong damping attribute. This gives the eco-friendly, advanced HDR rubber bearing higher functionality, similar to that of conventional rubber bearings. 

2.Cost reduction 
Our HDR rubber bearing has 20% higher damping performance than conventional HDR. It is therefore more effective, while its design makes it compact and slim at bottom. It helps reduce overall costs of bridges. 

3.Superior deformation performance 
The HDR outperforms natural rubber bearings in terms of deformation resistance. It functions steadily during repeated deformation forces of a major earthquake. Various tests of dependability and a shear deformation performance test have proved it to be reliable in long-term durability and performance safety.


High damping rubber bearing(HDRB) are used in bridges and constuction structures. 

It can achieve lateral and vertical damping effect, especially applicable to the basic vibration 

reducing system.

For the regions which have special requirements on the environment, such as residential 

apart buildings, office buildings and public parks etc, the bearings can also be widely used.


The advantage of isolation bearings
1. Vertical bearing capacity, horizontal restoring force and damping (energy absorption) trinity;
2. The hysteretic characteristic of support (load deformation curve) is full and the energy
consumption is remarkable;
3. Rubber formula improved, the equivalent damping ratio of more than 12%;
4. Low Maintenance management cost  (without other damping device);
5. No damage to the structure that remains due to the elastic response for high intensity earthquakes with no interruption of the structural function. This is a primary goal for strategic structures (hospitals, control rooms, ecc…) 
6.High damping bearing surface covered with rubber protective layer, protect the internal
rubber from ozone, ultraviolet light influence, have better aging resistance, 50 years
equivalent damping ratio is less than 2%;
7.HDR high damping rubber has low temperature dependence and is widely used in different climatic regions;
8.HDR high damping rubber, like natural rubber, has superior creep properties;
9.Capacity to reduce the seismic energy from the ground to the structure with consequent simplification of the structure design.
10.Very well known and used in many applications both for buildings and bridges.

As your request, the high damping rubber bearing can be manufactured in
rectangular or round shapes. Custom sizes and designs are also welcomed.
