Aohong manufactures high-performance PTFE Bearing Pads designed to provide low-friction sliding surfaces for bridge structures and heavy engineering projects. These pads combine laminated rubber layers with a bonded polytetrafluoroethylene (PTFE) sheet, offering excellent flexibility, rotational capacity, and horizontal displacement control. The dimpled PTFE surface, filled with lubricant, significantly reduces friction, allowing smooth expansion and contraction movements in bridge superstructures. Widely used in highway bridges, continuous beam bridges, and large-span structures, PTFE Bearing Pads meet EN 1337-2 and other international standards.

Structural Composition

PTFE Bearing Pads consist of multiple layers of natural or neoprene rubber, reinforced steel plates, and a bonded PTFE sliding surface. The PTFE layer, typically 1.5 mm to 3 mm thick, is engineered with dimples to retain lubricants, ensuring stable sliding and improved durability. The laminated design provides vertical stiffness to support heavy loads while enabling horizontal flexibility to accommodate seismic or thermal movements.

Features of PTFE Bearing Pads

• Low friction coefficient for smooth sliding movements.
• High vertical load capacity with excellent horizontal displacement.
• Dimpled PTFE layer retains lubricant for extended performance.
• Suitable for rotational and shear movements of beam ends.
• Resistant to temperature variations from -40°C to +60°C.
• Complies with BS EN 1337-2 and other bridge engineering standards.
