Product Description
Seismic resistance neoprene isolators for bridge
Seismic resistance neoprene isolators for bridge are made of multilayer Neoprene/EPDM/natural rubber with or without sheet steel after inlay, conglutinate, vulcanization. It has enough vertical stiffness to support vertical load, and it could deliver the pressure of superstructure to abutment. 

Applications

Seismic resistance neoprene isolators for bridge can be used for steel structures, pre-cast concrete structures, standard concrete slabs, and anywhere needs vibratuin isolation. This type of bearings provide an excellent economic solution for applications where structure movements, longitudinal, transverse and rotational are small, provide vibration isolation and are generally simple to install.
