WIPER 80X88X8/6 NBR

SKR205-080-088-008N is a wiper and can be used in rod applications. The material used on this wiper is made of NBR 90 shore.

The dimensions has an inner diameter of 80 mm, an outer diameter of 88 mm and a height of 8/6 mm.

About the sealing profile SKR205

SKR205 Combined double wipers are designed to prevent hydraulic cylinders from any unfavourable incoming particles from an external environment 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 SKR205 double wipers, they must be combined with suitable rod seals or a 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.
