FR Guiding Element
Descriptions
The Profile FR guide ring is open and therefore lends itself to easy assembly. It is
extraordinarily wear-resistant and suitable for rod guiding. The use of this guide ring
simplifies the design of cylinder heads.
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.
• Significantly higher permissible loading
pressure compared with other guidance
tape materials.
• Dimensions according to DIN 10766.
• Any desired nominal diameter available
due to use of machining technique.
• Installation in closed and undercut
housings.
Range of application
Guiding element for rods in hydraulic cylinders.

Installation
For surface requirements, see 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 millimetre or half-millimetre.
The calculation of the permissible radial force is based on the projected area d × L.
Example: permissible radial force FR for a rod 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“ (rod) = π × (d + S) – k
