PTFE Plates
In addition to the vertical stiffness and elastic deformation of the ordinary plate rubber bearings, the polytetrafluoroethylene PTFE sliding bearing can bear vertical load and adapt to the rotation of the beam end. The low friction coefficient of PTFE plate and stainless steel plates (F = 0.08) can make the upper horizontal displacement of bridge is not restricted, so as to increase the service life of bridge support.
