Product Name: Elastomeric Bearing Pad for Bridge Rubber Bearing Pad Neoprene Bearing Pads Model NO.: A-24 Material: Prestressed Bridge Stress Characteristics: Arch Bridge Scale: Large Bridge Usage: Over Water Bridge, Tractor Bridge, Highway Bridge Across Way: Fixed Bridge Life: Permanent Bridge Certification: DIN, JIS, GB, BS, ASTM Color: Black or Customized Size: Customized Trademark: GOFAI Transport Package: Cartons Specification: customization Origin: China Product Description Elastomeric Bearings are designed for use in bridge and building construction - providing point load substructure support with multi-directional movement and rotation capacity. Customer Specific Designs Steel Plate reinforced Elastomeric Bearings are manufactured in a range of standard plan sizes. Molds are adjustable in height, up to the limitation of stability for a given minimum plan size of bearing. Special designs using either nonstandard plan sizes and/or specially fabricated molds to customer's requirements are available.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 the reinforced elastomeric bearing and non-reinforced elastomeric bearing. And the reinforced elastomeric also can be divided into the laminated bearing pad and PTFE sliding elastomeric bearing. Non-reinforced elastomeric bearing, also called plain elastomeric bearing, is generally used for small displacement bridges with simple structures.PTFE Sliding Elastomeric Bearing - Freely SlidingPTFE 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 the laminated elastomeric bearing pad, it is added a layer of polytetrafluoroethylene which has a low friction coefficient, thus the beam end can freely slide on bearing surface and the horizontal displacement will not be limited. PTFE sliding elastomeric bearing is suitable for bridges with medium or small loading and large displacement.ApplicationElastomeric bearing is suitable for large displacement bridges with the structure of large span, multi-span continuous beam, simply supported beam and continuous slabs. It can also be used as the sliding block for pushing of continuous beam and cross sliding of a T-shaped beam.FeaturesLow friction coefficient. The beam end can freely slide on the PTFE surface.Dimples on the surface. With dimples on PTFE for containing a lubricant to ease the sliding movements.Superior flexibility. Adapt to the rotation of the beam end.Large shear deformation. It can satisfy the horizontal displacement of the superstructure.Excellent isolation effect. It can reduce the impact force from the live load and earthquake.A section of PTFE laminated elastomeric bearing.
