Function
Guide strips made of PTFE compounds serve to guide pistons and rods. They prevent metallic contact of the machine parts and absorb the transverse force that occurs. Guide elements made of PTFE compounds are characterised by outstanding friction behaviour which minimises the stick-slip effect. In addition they exhibit high thermal and chemical resistance. PTFE guide strips are suitable for medium surface pressure.

Installation
Guide strips are produced on rolls and cut to the required length. 
There are three different cutting types: 30°, 90°, ST. 
30° = for better press force distribution and to facilitate installation
90° = simple cut
ST = for swivel movements

The following formulae are used to calculate the required lengths
Guiding a rod:
L = 3.11 x (Ød + S) - 1
Guiding a piston:
L = 3.11 x (ØD - S) - 1
