The HDR high damping rubber bearing, Its structure is the same as ordinary laminated rubber bearings, high
damping rubber bearing is improved through rubber formula, so that the rubber material damping is increased,
the bearing's damping ratio can reach 15-18%. This series of bearing is suitable for  9 degrees earthquake
intensity area of highway and municipal bridge.

Kinds of High Damping Rubber Bearing

(1)Floating vibration isolation track/board support
Floating vibration isolation track/board support is composed of rubber damping bearing or steel spring
damping bearing and viscous coupling wall-beam, its basic principle is set the damping bearing between
rail/plate and foundation, this product has good shock absorption performance, suitable for railway, lightrail
and underground rail suspension; All kinds of mechanical vibration isolation

(2)Cultural relics isolation box
Cultural relics isolation box is composed of core shock/vibration base and housing, has a good vibration
damping/ability, apply to earthquake action and external environment vibration excitation of the protection of
cultural relics.

(3)vibration isolation platform 
Vibration isolation platform has core energy shock/vibration bearing, has a good ability to reduce shock/
vibration, used for all kinds of high precision equipment instrument, banking system, network system, and
other important data protection, prevent earthquake and vibration causing damage to the environment.

(4)Bridge isolation bearing
Bridge isolation bearing is very stiff in nature, however, during earthquake, it becomes very flexible in
horizontal direction so that they can reduce the earthquake force upon the bridges by changing its own shape.
Most of all, it can spring back to its original shape after earthquake owing to high elastomeric property.

Successful case of the isolation bearing
as early as the mid-1990-s, building isolation rubber bearing showed its excellent isolation performance. The
region of an earthquake, Osaka and kobe, Japan is the real one. On January 17, 1995, Japan kobea 7.2 -
magnitude earthquake, caused the shocking heavy losses. In the earthquake, 35 kilometers from the
epicenter of the west of the men in the post office base isolation technology has played a very good isolation
damping effect, it is in the field of earthquake hazard level has reached the degree of 7 (equivalent to China's
earthquake intensity of 9~10 degrees), in the earthquake and after the earthquake, the whole building is as
