The Parker Prädifa FR rod guide ring made of fabric phenolic resin laminate is intended for use in hydraulic cylinders. The guide ring is created in a slit form (45 ° cut) to enable installation. In addition, the slit version ensures that the system pressure can pass toward the seal, taking thermal expansions into account.

The FR guide ring is exceptionally pressure-resistant and wear-resistant.

Pressure resistance is much higher than that of guiding elements made of other plastics.

After installation, the FR guide ring has an interference fit against the bottom of the groove.

• Minimal play due to extremely small manufacturing tolerances of the guiding elements.
• Vibration absorption effect.
• Extreme wear resistance.
• Improved sliding properties due to surface structure.
• Significantly higher permissible loading pressure compared with other guidance tape materials.
• Dimensions according to DIN.
• Any desired nominal diameter available due to the use of machining.
• Installation in closed and undercut.

Installation

For surface requirements, see the chapter „General Installation Guidelines“.

For nonferrous and light metal pistons, please use our F3 guidance tape profile (PTFE with carbon filler).

The installed rings must have a gap „k“ between their diagonally cut ends:

k = 0.008 x d + 2

The calculated values for „k“ are rounded up to the nearest millimeter or half-millimeter.
