Bridge Bearing as an indication of quality. All bearings that support bridges or highway overpasses use Natural Rubber compounds, so the molded product has high tensile and elongation characteristics and minimal permanent set and creep. Similarly, they must pass rigid tests in ozone and oxygen resistance. When the pads are used for vibration isolation in supporting buildings or components such as structural floors, secondary floating floors, maximum "Dynamic Stiffness" is another specified characteristic. This is important as the Dynamic Stiffness, Deflection and the shape of the Load Deflection curve controls frequency. Bearing pads are always solid pads (unlike our waffle pads), because loadings per square inch are high, often in the range of 1000psi. Capacities are controlled by area, hardness (durometer), thickness and perimeter relative to the loaded area. Most of the time we design these pads to specific requirements as explained in Bulletin AB-104-2 in the Architectural Section, but we thought it would be helpful to offer some stock sizes for immediate shipment. While they can certainly be used in acoustical applications, there is a constant contractor need for a high capacity pad for pipe supports, structural supports, etc., in the load range of these pads. Pads can be stacked with 1/8" steel plates between them up to 250psi for higher deflections and greater efficiency. Higher loadings per square inch require bonded inserts to avoid pancaking. Maximum deflection: 1/8". Measures 10" length by 10" width by 1" thick. Maximum load: 25000lbs.
