Crossflon® XF225 Technical Data

Crossflon® XF225 is an enhanced form of PTFE, which offers substantially improved performance over the materials traditionally used in the manufacture of skidway plates and slide bearings, namely virgin and 25% glass fibre filled PTFE.

As the technical data shows, Crossflon® XF225 can accommodate significantly higher pressure than 25% glass fibre filled PTFE and yet has coefficient of friction values which are comparable with those of virgin PTFE.

Selection Guide

  • Calculate the overall load of the structure as this will indicate the total area of the Crossflon® slide bearing required at an appropriate temperature and pressure.
  • Consider the function and rigidity of the structure to determine the quantity and positions of the Crossflon® slide bearings.
  • Take account of any unusual conditions that will affect the Crossflon® slide bearing during operation, such as the temperature at the sliding interface, angular misalignment and the need for acoustic or vibration dampening.
  • The type of adhesive used is determined by the temperature range at which the Crossflon® slide bearings will be operating. We ask therefore that this information is specified on all enquires.
  • Determine the most suitable method of fixing the Crossflon® slide bearings to the installation.
  • Consider the operating environment and select the type of steel for the backing plates accordingly.
  • If you have any difficulty in specifying your Crossflon® slide bearings, please contact us for assistance.
