PARKER FC GUIDE RING

    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 F
    R 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
