About the sealing profile FOE251

FOE251 POM Piston Rod Guide Ring Wears are used in both piston and rod applications which are produced from polyacetal (POM) that is alloyed with fiberglass. The ring wears are produced with a standard 45 degree cut and appropriate “K” gap adjustment. FOE251 POM Piston Rod Ring Wears have a resistance capacity of up to 40 Newton/mm2 radial load.

About the material POM

Polyacetal (POM) (Polyoxymethylene) materials are used as back-up rings or guidening element materials in hydraulic and pneumatic systems. There are two types of POM, filled with or without fibreglass, depending on their use. Despite working temperatures ranging from -40°C to +140°C, real dimensions can not remain stable in excess of 100°C. It can be used safely with mineral oils and HFA, HFB type oils. Types with added fibreglass provide longer lasting contact pressure resistance.
