- Selection & installation guide
  
  PTFE slide bearings can be fixed to the installation by full welding, tack welding, mortar embedment or bolting.

SLIDE BEARINGS

Our PTFE slide bearings are offered in a range of configurations although each is designed to suit the specific application. A typical slide bearing element consists of 2.5mm thick PTFE (reinforced or virgin PTFE) hot cure factory bonded using our proprietary process to a 3mm thick steel backing plate for welding to the installation. Alternative material thicknesses and grades can be supplied to suit any application. Take a look at our typical configurations for more information.

PTFE slide bearings employ either a reinforced or virgin PTFE at the operating surface. Reinforced PTFE can accommodate loads of 18 MPa (184 kg/cm2) and virgin PTFE can accommodate loads of 7 MPa (71 kg/cm2). The load-bearing capacity of these materials can be increased by containing them in a recessed steel backing plate.

We’ve documented some of our typical configurations for PTFE slide bearings and skidway plates below. We also have expertise in tailoring specifications for bespoke projects.
