Product Description Lead rubber bearings are constructed by
vertically inserting a lead core in the center of the rubber
bearing.Lead exhibits a notably low yield stress,
approximately 7MPa, and favourable fatigue properties when
subjected to plastic deformations. This unique
combination allows lead rubber bearings to effectively dissipate
the seismic energy, with the potential to achieve the
damping ratio up to 25%.This product is in
compliance with the following
standards:"Rubber bearings -
Part 2: Elastomeric seismic-protection
isolators for bridges" GB/T 20688.2-2006 "Rubber
