STE802-050-036-007N is a piston seal that works as single acting and can be used in piston applications. The material used on this piston seal is made of NBR.
The dimensions has an inner diameter of 36 mm, an outer diameter of 50 mm and a height of 7 mm.
About the sealing profile STE802
STE802 Pneumatic piston seals are used in pneumatic cylinders with low friction force due to their special profiled dynamic sealing lip. Standard production of STE802 Pneumatic piston seals is from PU and NBR materials. STE802 seals can be used safely in aluminum pneumatic cylinders although air in the system is not conditioned.
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.
