TYPES OF ELASTOMERIC BEEARING PADS
Non-Reinforced elastomeric pad
Nonreinforced bearing devices are best specified when the load, rotation and horizontal deflection are
minimal.
Laminated elastomeric bearing pad
The addition of internal steel plates (or laminates) increases the vertical load bearing capacity
and the amount of horizontal deflection which can be accommodated by the bearing device.
Laminated bearing assemblies are molded to any shape or size. The internal steel plates are
vulcanize-bonded to alternating layers of elastomer during the molding process.
Elastomeric Bearing Components- Sliding Design
For applications where horizontal displacements exceed +/-2 inches(50mm), sliding elastomeric
bearing assemblies may provide an economical solution.The addition of a low-friction sliding
surface allows a standard laminated elastomeric bearing device to accommodate unlimited
horizontal displacement without increasing the height of the bearing assembly. bearings are
flexible support pointsused in the construction of viaducts and bridges.
RUBBER MATERIALS
Natural Rubber : applicable temperature -40° C~50° C.
Neoprene Rubber: applicable temperature -25° C~60° C.
Normally, The rubber material for elastomeric bearings are requested
to used in different areas,sometimes in different projects.
What does the surface of good elastomeric bearing pads look like?
1.The surface is smooth without any raised points.
2.Rubber material color- uniform and thick.
3.Rubber material could be kept color and brightness in air longer.
