FRE external face seal
SLIDING SURFACE Ra 0.4 / STATIC SURFACES Ra 0.8
Face seals are dynamic seals originally produced in NBR for slow movement and a lack of pressure, keeping dirt far from mechanical components. The use of more high-performance materials (e.g. SINTEK HTPU) allows for increased resistance to wear and to the dynamic conditions.
Certain dimensions also enable resistance to pressure.
