HUNGER AI WIPER SEAL

    AI WIPER SEAL

    The HUNGER wiper ring type AI has the function to keep out extremely fine dust, metal particles, grains of sand etc. such that the bearing elements and seals behind it are not subjected to premature wear as a result of contaminant ingress.

    The AI wiper can be used with mineral oils and many other types of hydraulic fluid.

    Special versions are available for use at high ambient temperatures.

    Care must be taken to ensure that there is no pressure build-up, including grease lubricant pressure, on the inside of the wiper.
