Category:

The Parker Prädifa piston guidance tape profile F3 was specially designed for use on hydraulic cylinders.

Its advantages:

  • We can supply these tapes either cut to length or by meter so that you can cut it according to your requirements
  • High load capacity (compressive strength ) low wear and reduced friction due to a special additive of bronze to the PTFE material
  • No tendency to stick-slip in the case of low sliding speeds and high radial forces.
  • Simple groove designs without metallic contact of the sliding surfaces.
  • Available in practical dimensions.

Field of application:

Working temp.:          – 100 to + 200 °C

Surface speed:            ≤ 5 m/s

Installation:

Refer to “General installation guidelines” for cylinder bore running surface.

For cylinders made of alloys and light metal, such as high-grade steel, we recommend the use of compound W5038.

The groove diameter is calculated by d = D-2S. The gap size -e“ between the cylinder and piston serves as a maximum dimension and should not be exceeded.

Compound

The standard compound Parker Praedifa W5140 is a PTFE-material with 40 % bronze addictive. The guidance tape F3 is – on request – also available with 60% bronze addictive (W5160)
