GB/T 17955 Approved Natural Rubber Seismic Isolation Bridge Bearing. Made of natural rubber and multi-layer steel plates, integrally formed by high-temperature vulcanization. It has functions of vertical load bearing, horizontal shearing, temperature expansion displace. Composed of steel pot body, rubber pressure block, PTFE sliding plate and sealing structure. It features large tonnage load capacity, large displacement and flexible rotation angle. With waterproof. Adopting spherical friction rotation structure, breaking the rotation limitation of traditional bearings, supporting large-angle multi-directional rotation, large displacement sliding. Including lead core seismic isolation, high damping HDR, LNR and friction pendulum seismic isolation types. It integrates load bearing, shock absorption, seismic isolation and energy. Including ordinary grid bearing, tension resistant bearing and seismic tension compression bearing. It has functions of vertical load bearing, horizontal displacement, multi-angle rotation.
