The description of isolation bearings
 
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, so that 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.
 
By improving the formula, so that the rubber material damping is increased, so that
the bearing's damping ratio increase, achieve the isolation effect.

The types of isolation bearings
 
1.According to the Isolation property points
(1)Ordinary rubber isolation bearing
(2) Lead rubber bearings
(3)High-performance isolation bearings
(4)Three-dimensional isolation bearing
2.According to the vibration territory point
(1)Floating vibration isolation track/board support
(2)Cultural relics isolation box
(3)vibration isolation platform 
(4)Bridge isolation bearing

The advantage of isolation bearings
 
1.The trinity of the vertical bearing capacity, level of restoring force and damping(energy absorption) 
2.Bearing hysteresis characteristics (load -deformation curve) fully, energy consumption significantly
3.Rubber formula improvement, the equivalent damping ratio can reach more than12%
4.Low maintenance cost (no other damping device)
5.Little residual deformation after the big earthquake, don't need to replace
6.High damping bearing surface covered with rubber protection cover, which prevents the internal 
rubber from being affected by ozone, ultraviolet ray, has better aging resistance, 50 years of 
equivalent damping ratio less than 2%
7.Its low temperature dependency, widely used in different climate regions
8.HDR high damping rubber and natural rubber with superior creep properties
9.Environmental protection,no pollution

As your request, the high damping rubber bearing can be manufactured in rectangular or round shapes. 
Custom sizes and designs are also welcomed.
 
Q :
What is the good successful case of the isolation bearing?

 
A:In fact, 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 usual.

Q:How can I get some samples?
A:We are honored to offer you samples. New clients are expected to pay for the
postage, the samples are free for you, this charge will be deducted from the
payment for formal order.
