Materials
Polyoxymethylene - POM
Polyoxymethylene (POM or polyacetal) belongs to the thermoplastics, which have a number of advantages - strong mechanical resistance, good creep strength, high resistance to shocks, particularly at low temperatures, good wear resistance, good sliding coefficient, excellent machinability and good dielectric properties. The low water absorption coefficient, unlike polyamide (PA), also gives this material an excellent dimensional stability.

| Temperature range | -50°C/+115°C |
Design guidelines
Guide sizing
The following formulas calculate the height "H" of the rod guide holder while taking account of the gap "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)
where:
H = Min. height of the 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.
