Description: 

Linear Natural Rubber Bearing is made from multiple layers of rubber sheets and steel plates via vulcanization,connected by top and bottom steel plate, and connection accessories. It has excellent seismic isolation performance to effectively reduce the bridge and construction damage caused by earthquake.

Features：

•  High vertical stiffness 

•  Excellent horizontal deformation to absorb shock energy effectively

•  Strong durability  

•  Economical and high performance for lower total construction

•  Easy installation and replacement for lower maintenance.

Types: 

•  Diameter 400mm to 1500mm

•  Custom dimensions are available for special applications.

Design and fabrication standard:

•  GB 20688.2 Rubber Bearing - Elastomeric seismic protection isolators for bridges

•  GB 20688.3 Rubber Bearing - Elastomeric seismic protection isolators for buildings

•  In reference with AASHTO Guide specification for Seismic Isolation Design

•  In reference with 15129:2009 Anti-seismic devices

•  In reference with EN1337-3
