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.
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,some
times in different projects. Please name the rubber material when contact us.
European standard and ASTM standard.
Preparation of rubber compound according to specification required 1. Preparation of steel plates 2. Application of bonding agent to steel plates 3. Assembly of compound and plates 4. Compression moulding 5. Performance Test 6. Ready for installation
TESTINGS AND INSPECTIONS
What tests we can do? 1.Material Testings, which are about physical properties of matierals.They are normally listed on the standards. 2. Production Inspections, which control the whole producion process by third department as customers' requests. 3.Finished product quality control by testing. Tested in our own lab or in a third department lab as
SGS or any lab in your countries. The whole test procedure is complicated but necessary, How to make it easy? we can supply
samplies for our clients to test directly.
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.
