Safety Warning

Full Product Description

The FU 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 special geometry of the dynamic sliding surface avoids edge compression, resulting in more favorable load distribution.

The FU 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 FU guide ring has an interference fit against the bottom of the groove.

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

• 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 ISO 10766.
• Any desired nominal diameter available due to use of machining technique.
• Installation in closed and undercut housings.
