PTFE Bridge Bearings

In situations where the controlled dilation of resting surfaces of bridges and other infrastructures needs to be guaranteed for a long time, it is crucial for the quality of materials to be suited to the intended application.

Our Italian supplier, Guarniflon® S.p.A, is one of only a handful of companies worldwide that can produce PTFE dimpled sheets in accordance with standards EN 1337-2 in a wide range of standard and cut-to-order sizes.

Out in the field PTFE bridge bearings are often referred to with such names as:

➡️ Expansion Bearings
➡️ Seismic Bearings
➡️ PTFE Sliding Bearings
➡️ PTFE Bearing Pads

Our Guarniflon PTFE dimpled sheets are designed to hold grease for the lifetime of the bridge bearing, as they are almost impossible to grease after installation.

Dimpled discs for bridge bearing applications

Largely used in the engineering and construction field, dimpled sheets and discs are the perfect solution to thermal expansion and load problems usually connected with structural elements.

One of the most common applications for dimpled sheets is the insertion between 2 movable elements (i.e. bridges) working as a self-lubricating system exempt from any need of maintenance.

Processed and certified in accordance with the international standard EN 1337-2.

The 3.1 certificate is supplied together with orders.

The most common sizes are available ex stock at Guarniflon and can be processed one side etched for bonding to different kinds of materials.

Supply Services Limited can import these items with our regular stock shipments by sea or urgently via air.

Dimpled sheets and discs

Our Guarniflon bridge bearing materials are available to be supplied from Virgin PTFE (take a look at our product page) or compounded PTFE sheets.

Due to the dimpled sheets special surface they are frequently used in the engineering and construction field.

Dimpled PTFE sheets and discs is the perfect material to solve thermal expansion and load problems usually connected with structural elements.
