SAB Wiper
SAB
(Bi-Directional Rod Wiper)
The functions of the 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 asymmetrical lips are designed to differentiate the behavior 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.
This seal is produced in polyurethane and ensures excellent properties in case of dry run, an increased wear resistance and extended service life due to good resistance against ozone and radiation caused by weather conditions.
