Two functions – sealed and dust-proof all in one.
Minimum space requirements meet safe availability and ideal profile finish.
Simple structure, efficient manufacturing technology.
The FEM type piston rod seal/dust ring can also be used in dry/oil-free air after initial lubrication due to the special geometry of the seal and dust lip plus the special material.
Due to functional lip optimization adjustment use its smooth running.
As the components are composed of a single polymer material, there is no corrosion.
