HUNGER AI-SF WIPER SEAL

    AI-SF WIPER SEAL

    New developed, single acting wiper profile with drain shield function. Practical for vertical working hydraulic cylinder applications where fluids or fine dirt particles from above may ingress and harm sealing and bearing systems.

    Expensive breakdowns and damage by corrosion of grooves can be avoided. AI-SF has implemented radial support-elements on the back side keeping contact friction low in case of side load deflection.

    If cylinder working situation demands an upgrade a standard wiper version AI can easily be exchanged by AI-SF without any changes on the installation grooves or gland design.
