AF-480 & AF-580

The wiper/scraper possesses a sturdy profile with a wiper lip protruding on the air side.
A radius exists on the outermost circumference in order to be able to fit an O-ring.
Wiper/scraper rings are manufactured from specially modified PTFE materials. The
compound, AF-5640 (PTFE bronze), is standard material in construction (MOC), which
is used in hydraulics applications. This material is particularly superior in respect of
very high abrasion resistance, extrusion resistant, very good shearing characteristics
and very good thermal and chemical resistance.

Advantages:
  • Very low friction especially start friction
  • Very small groove design
  • Very good scraping effect even when dirt has fastened onto shaft from airside
  • To be used in combination there is a seal as it has a good pump effect
  • Machined up 1200 mm

Limitations on Use*  
Velocity reciprocating to 15 m/s
Temperature -40 to +200 °C (depending on O-ring material)
