Jing lead core rubber bearings with competitive price
Lead rubber bearing, applied to building and bridge constructions, is a practical and cost-effective choice for seismic isolation. It is composed of laminated elastomeric bearing pad, top and bottom sealing & connecting plates and lead plug inserted in the middle of the bearing as shown in the following picture.
Specification
Name: LRB bearing
Material: rubber
Brand : JINGTONG
CR suit temperaturer : CR -25°C~+60°C

CR suit temperaturer : CR -25°C~+60°C
FeaturesStiff 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 bilinear behavior shown as the picturesSize a or do (mm) |

Base isolation is a technique developed to prevent or minimise damage to buildings during an earthquake. It has been used in New Zealand, as well as in India, Japan, Italy and the USA.
A fixed-base building (built directly on the ground) will move with an earthquake's motion and can sustain extensive damage as a result.
When a building is built away (isolated) from the ground, resting on flexible bearings or pads known as base isolators, it will only move a little or not at all during an earthquake.
