PTFE dimpled sheet / PTFE bridge bearing pads

A PTFE dimpled sheet is a specially molded PTFEsheet with a surface textured with uniformly spaced dimples. These dimples minimize contact area while ensuring high load transfer capability. The reduced friction makes them ideal as sliding components in bridge bearings, expansion joints, and other structural support systems.

PTFE(polytetrafluoroethylene) dimpled sheets, also known as PTFEbearing pads, are specialized sheets used in various engineering and construction applications, particularly in bridge and structural engineering. They feature a dimpled surface that facilitates smooth, low-friction movement between two surfaces, often acting as a self-lubricating system. These sheets are known for their chemical inertness, temperature resistance, and ability to withstand high loads.

Also known as PTFE bridge bearing pads, these components are typically bonded with elastomeric or stainless-steel backing to create high-performance sliding bearings.

PTFE(polytetrafluoroethylene) bridge bearing pads, also known as structural bearings, are crucial components in bridge construction and other structures requiring movement accommodation. These pads, often made with a PTFEsheet bonded to an elastomeric bearing, allow for smooth sliding and rotation under load, accommodating thermal expansion, contraction, and other movements. Their low friction coefficient and self-lubricating properties make them highly effective for these applications.

• Elastomeric bearings with PTFE sliding sheet: These bearings combine the load-bearing capacity of elastomeric pads with the sliding capabilities of PTFE.
• Rectangular and round PTFE bearing pads: Depending on the bridge design, either rectangular or round PTFE bearing pads are used to accommodate different load and movement requirements.

• Bridges: PTFE bearing pads are commonly used in bridges to accommodate thermal expansion, contraction, and other movements.
• Buildings: They can also be used in buildings to support beams and girders, allowing for movement and reducing stress.
• Pipelines: PTFE bearing pads can be used in pipelines to accommodate movement and reduce stress on the pipeline.
• Other structures: They can also be used in other structures where movement and load transfer are required.
