codes of PTFE slide plate-type elastometic bearing:GJZF4 for rectangular type and GYXF4 for circular type.In plate bearing surface adhesion a layer of 1.5mm-3mm PTFE can make it.In addition to vertical stiffness ,elastic deformation, bear vertical load and adapt to the girder movement that a common slab rubber bearing has,it takes the advantage of low friction coefficient(u=<0.08) between PTPE and the stainless steel in the bottom of the girder, makes the bridge superstructure's horizontal displacement unrestricted.
