FC Guiding Element
Descriptions
FC guiding tapes are extremely wear-resistant and suitable for piston and rod guiding. They can be cut to any desired length (max. 5.5 m). The tapes are wound on flat
coils with a core diameter of approximately 120 mm. FC guiding tape stock is sold in
packaging units of 5.5-metre rolls (desired length to be cut by the customer).
Features
• 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.
• Can be elongated or compressed within
limited diameter ranges (preferably
≥ 100 mm).
• Significantly higher permissible loading
pressure compared with other guidance
tape materials.
• Any desired nominal diameter available
due to use of machining technique.
• Suitable for cylinder repairs.
• Ideally suited for large-diameters.
• Bulk material.
• Installation in closed and undercut
housings.
Range of application
Guiding element for pistons and rods in hydraulic cylinders.

Installation
For piston and rod diameters up to 100 mm, we recommend our FR/FK guide rings.
For surface requirements, see chapter „General Installation Guidelines“.
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 millimetre.
The calculation of the permissible radial force is based on the projected area D × H
(cylinder) or d × H (rod).
Example: permissible radial force FR for a cylinder diameter of D = 80 mm, length L =
15 mm, compound Q5038T and safety factor 4:
Recommendation for determing the safety factor ν: ν > 3
Calculation of elongated length
“U“ (piston) = π × (D – S) – k
Calculation of elongated length
“U“ (rod) = π × (d + S) -k
