2Structural Bearing AssembliesVersiflex™ HLMR Disc Bearing Assemblies

Disc Bearings consist of an elastomeric disc made of unconfined polyether-urethane polymer to accommodate rotation between two metal plates. The vertical loads aretransferred by the elastomeric disc.

Horizontal shear forces are transmitted between upper and lowerplates by a dowel pin mechanism in the center of the bearing.

2Structural Bearing AssembliesIsolation Bearing Systems

• Isolation Bearing Systems consist of three components – rubber, steel plates and a lead core

• Ease of handling and installation, same as elastomeric bearing

• Proven performance in real earthquakes

• No need for replacement after an earthquake

• Minimum ½” thick external cover rubber

2Structural Bearing AssembliesIsolation Bearing Systems
