Crossflon® Slide Bearings

PTFE Sliding Plates







Crossflon® Slide Bearing 

Crossflon® slide bearings are used in a wide range of applications including pipe lines, heat exchangers, pressure vessels, storage tanks, industrial machinery, buildings and bridges.

A Crossflon® slide bearing normally comprises of an upper element and a lower element, which operate by sliding against one another. The upper element is generally larger than the lower element by the amount of the anticipated movement. This ensures that the lower element is subjected to uniform load throughout motion and excludes foreign matter from the sliding interface.

Advantages of Crossflon® Slide Bearings

  • Crossflon® PTFE has the lowest coefficient of friction of any known solid engineered material including lubricated metal and there is no stick / slip action.
  • Crossflon® XF225 is unaffected by water as the moisture absorption is less than 0.01%.
  • The life of Crossflon® XF225 is indefinite as it is unaffected by chemicals and weather.
  • Not subject to fatigue failure.
  • Ease of installation.
  • Shear value of the bond exceeds that of Crossflon® PTFE.
  • Far less bulky than alternative assemblies.
  • Operating temperature ranges from -40ºC to +120ºC. Alternative bonding sytems are available for temperatures outside this range.
  • Maintenance is not required. Capable of operating completely dry as Crossflon® XF225 will never cold weld to itself.
  • Provides electrical and thermal insulation thereby minimising galvanic corrosion and heat loss.
  • Vibration dampening.
  • Able to absorb small particles without increasing the coefficient of friction.
  • Crossflon® XF225 is chemically inert.
  • Able to accommodate minor misalignment during construction.
