Function
FRK 01 guide rings made of PTFE compounds serve to guide pistons, 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 rings are suitable for medium surface pressures.

Installation
Guide rings made of PTFE compounds are supplied as stretched, pre-cut PTFE guide strips which can easily be installed in closed installation grooves. The edge chamfers also facilitate installation. With one-sided surface structured material, care must be taken to ensure that the profiled surface is always installed as the contact surface.

Remarks
Standard PTFE guide rings are supplied as strips with a 30° diagonal cut and a PTFE-bronze compound. Should you require non-standard cutting types or materials, please include these in your order.
