High damping rubber bearing (HDR), similar with lead rubber bearing, belongs to seismic isolation bearing. It is composed of special rubber with excellent damping attribute, sandwiched together with layers of steel. Damping is an influence within or upon an oscillatory system that has the effect of reducing, restricting or preventing its...

Lead rubber bearing (LRB), similar with high damping rubber bearing, belongs to seismic isolation bearing. It is composed of multiple layers of elastomeric material and vulcanized reinforced steel plates with a central lead core. Generally, the rubber for making lead rubber bearing is nature rubber and the shore hardness of the rubber changes from...

Seismic isolation bearing, as it name implies, is a kind of bridge bearing designed to minimize forces and displacements during an earthquake. Generally, this kind of bridge bearing can be divided high damping rubber bearing and lead rubber bearing. High damping rubber bearing utilizes the high damping performance can reduce the vibration...

Spherical bearing, also called spherical bridge bearing, is one type of bridge bearings with large rotation capacity. Similar with pot bearing, spherical bearing also can be divided into three types: fixed spherical bearing, guided spherical bearing and free sliding spherical bearing. With high strengthened steel body, spherical bearing is...

Pot bearing, also known as pot rubber bearing, with elastomeric bearing embedded inside of the steel plate, can be divided into fixed pot bearing, guided pot bearing and free sliding pot bearing. Pot bearings are special types of bridge bearings for taking large loads, large horizontal displacements and large rotation requirements in confined...

PTFE sliding elastomeric bearing, one type of elastomeric bearing pad, is formed by adhering a layer of 1.5 mm to 3 mm thickness PTFE on the surface of laminated elastomeric bearing pad. Compared with laminated elastomeric bearing pad, it is added a layer of polytetrafluoroethylene which has low friction coefficient, thus the beam end can freely...

Laminated elastomeric bearing pad, one type of reinforced elastomeric bearings, is made of multi-layer rubber and reinforced with steel plate through sulfuration and adhesion. Compared with non-reinforced elastomeric bearing, it has sufficient vertical rigidity which can reliably transfer the concentrated down-loads and impact loads of the...

Reinforced or Non-Reinforced Elastomeric Bearing Pad Elastomeric bearing, also called elastomeric bearing pad, is one type of bridge bearings. According to the structure of elastomeric bearing, it can be divided into reinforced elastomeric bearing and non-reinforced elastomeric bearing. And the reinforced elastomeric also can be divided into...

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...
