Non-reinforced elastomeric bearing

Non-reinforced elastomeric bearing, also called plain elastomeric bearing, is the common and economical type of elastomeric bearing. It is manufactured from high quality nature rubber or neoprene rubber to meet AASHTO and many other standards, then molded to any required shape. Non-reinforced elastomeric bearing not only allows for expansion and contraction of precast or steel components but also can minimize the vibration effects of the structure and absorb the noise. Thus, this kind of bearings with different thicknesses can suit for a variety of purposes in the bridge and construction industries. While compared with pot bearing and spherical bearing, non-reinforced elastomeric bearing does not have the steel plate outside of the rubber pad, thus it is more suitable for small displacement bridges with simple structures.
