Reliable, durable, and customizable engineering rubber products and bridge components for infrastructure projects worldwide.
PTFE sliding elastomeric bearing, one type of elastomeric bearing pad, is formed by adhering a layer of 2 mm to 3 mm thickness PTFE on the surface of laminated elastomeric bearing pad. Compared with laminated elastomeric bearing pad, it is added a layer of polytetrafluoroethylene which has 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.
Features：
Low friction coefficient. The beam end can freely slide on the PTFE surface.
Dimples on surface. With dimples on PTFE for contain lubricant to ease the sliding movements.
Superior flexibility. Adapt to the rotation of the beam end.
Large shear deformation. Can satisfy the horizontal displacement of the superstructure.
Excellent isolation effect. Can reduce the impact force from the live load and earthquake.

Round PTFE laminated bearing pad inner structure drawing：
Installation：
The Teflon laminated bearing pad should be horizontal installed. The PTFE board can not be placed on the bridge pier.
The PTFE bearing pad is commonly used assorted with steel plate, including top plate, stainless steel plate and bottom plate.
Silicone grease should be evenly distributed between Teflon plate and stainless steel plate.
Ensure right installation direction according to the direction guide on the stop plate.
Dust cover should be placed after installation.
Application： PTFE sliding elastomeric bearing is suitable for large displacement bridges with 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 T-shaped beam.
