    About the sealing profile SKR208

    SKR208 Combined double wipers are designed to prevent hydraulic cylinders from any unfavourable incoming particles from the outside and refine oil film thickness in the connecting rod of cylinders with their second sealing lip. In order to avoid any possible hydro dynamic pressure problems between the rod seals and the SKR208 double wipers, they must be combined with suitable rod seals or drainage channel must be opened in this area.

    About the material NBR

    Nitrile is a widely used nitrile butadiene and acrylo nitrile polymer. The NBR formulas typically contains between 30% and 50% acrylonitrile (ACN). The NBR which has a working temperature between -30°C and +105°C (peak temp. at +130°C) show extremely high resistance under different working conditions such as mineral oils (H, H-L and H-LP type lubricating oils) and grease and mineral based fire resistance oils (HFB and HFC group oils), vegetable and organic oils, and aliphatic hydrocarbons (propane, butane, petrol). NBR is not recommended for aromatic hydrocarbons (benzene, trichloroethylene, HFD type fire resistance oils), glycol and ether contained break hydraulics.
