Item Information

The FK 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 FK 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 FK 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.
• Easy snap assembly without assembly aids.
• Significantly higher permissible loading pressure compared with other guidance tape materials.
• Dimensions according to ISO 10766.
• Also available as bulk material.
• Any desired nominal diameter available due to use of machining technique.
• Installation in closed and undercut housings.

Range of application:
Guiding element for pistons and piston rods in hydraulic cylinders.
