The functions of the Aston Seals SAB bi-directional rod wiper are:

  • to prevent introduction of dust, dirt and foreign matter into the system; this is achieved by a special wiper lip which produces a very effective cleaning action, prevents the development of scores, protects the guiding parts and extends the service life of the axial moving rod seals.
  • to retain residual oil film on the rod; the asymmetric lips are designed to differentiate the behaviour of the lips on the static and dynamic surfaces: the static lips are flexible and more sensitive to pressure  fluctuations; the dynamic lip is shorter and stronger to concentrate load against the dynamic surface.

The material used to produce this wiper is a polyurethane compound that ensures excellent properties in case of dry run, an increased wear-resistance and an extended service life due to good resistance against ozone and radiation caused by weather conditions.

  • Retaining residual oil film
  • Extended service life
  • Insensitive to structural deflections
  • Excellent wear-resistance
  • Space-saving construction
  • No close tolerances are necessary
  • Easy installation without expensive auxiliaries
