Product Description
Lead Rubber Bearing
Product advantage
◊ Stiff and strong in vertical direction but flexible in horizontal direction.
◊ Absorb earthquake-generated force by changing the bearing’s shape.
◊ Allow the buildings to retain their original shapes and position owing to the high elastic force of rubber.
◊ Capable to adjust damping amount just by changing the number of lead plugs.
◊ Excellent vertical load capacity ranging from 5 tonf to 2000 tonf.
◊ Reduce the ground acceleration by extending the structure vibration period.
◊ High durable and elasticity of the rubber part – not suffer any damages during and after earthquake.
◊ Easy to install without a separated damper.
◊ Low maintenance.
◊ With stable bi-linear behavior shown as the above picture.
