The description of isolation bearings

Lead rubber bearing is based on general laminated rubber bearings,pouring the lead into the bearing center, which is a seismic bearing damping performance improvement of rubber bearings. By changing the lead core section size of the bearings, lead rubber bearing can change the effective level of equivalent stiffness and equivalent damping ratio.  
Our production capacity is not limited to this, please send your requirements to us.

The advantage of isolation bearings
1.Stiff and strong in vertical direction but flexible in horizontal direction.
2.Allow the buildings to retain their original shapes and position owing to the high elastic force of rubber.
3.Capable to adjust damping amount just by changing the number of lead plugs.
4.Excellent vertical load capacity ranging from 5 tons to 2000 tons.
5.Reduce the ground acceleration by extending the structure vibration period.
6.High durable and elasticity of the rubber part - not suffer any damages during and after earthquake.
7.Easy to install without a separated damper.
8.Low maintenance.
9.Stable bilinear behavior.

Bridge Construction Lead Rubber Bearings in Philippines

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

Q :
Where is the lead rubber bearing used to?

A:The product has been successfully used in a broad range of applications which include: bridges,
viaducts, high rise buildings, stadiums and dams.  

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.
