Product Description
Guide Ring FRI
The FRI Rod profile is a machined guide ring or wear ring with a 30° angle cut as standard, made from filled PTFE. In line with GB/T15242.4 standard. Designed apply please referring to Merkel FRI series standard and Trelleborg's GR series standard.
Substantial and improved lubrication conditions through the tear structures
Very good friction coefficient; no stick-slip effect
Good wear resistance; very long life
Increased absorption of foreign particles
Good vibration absorption

Non-metallic guide component for rods; for standardized housings amongst others, according to ISO 10766
no seizure due to metal/plastic material combination
medium load-bearing capacity
chamfered profile edges prevent pressing of edge into the corner radii of the housing groove simple snap in fitting

Guide sizing

The following formulas calculate the height "H" of the wear ring in the piston or rod seal while taking the gap into account "Z" necessary at the ends of the ring after fitting. This gap "Z" offsets the thermal expansion under the effects of temperature, and prevents intermediate pressures and drag pressures in the system.
H = (F x f) / (Ød1 x Cr)
H = Min. height of guide (mm)
F = Max. radial force (N)
f = Safety coefficient (we recommend 2)
Ød1 = Rod diameter (mm)
Cr = Permissible radial load in dynamic applications (N/mm²)

Types of cuts

The wear rings are made with a 30° angle cut as standard. Other types of cuts can be made on request, as shown in the diagram below.
