STE110-032-021-004 is a double acting piston seal that works as double acting and can be used in piston applications. The material used on this double acting piston seal is made of PU/NBR 98/80 shore. The maximum allowed pressure is 400 BAR.
The dimensions has an inner diameter of 21 mm, an outer diameter of 32 mm and a height of 4.2 mm.
About the sealing profile STE110
STE110 sealing elements are consisting of one PU ring and one NBR ring. These seals work as double acting. They are commonly used, thanks to their price-performance ratio.
About the material PU/NBR
PU is moulded with injection techniques. It has excellent mechanical properties such as high tensile strength, wear resistance, tear strength, and extrusion resistance. It offers a good resistance to air, ozone, mineral oils, grease and aliphatic hydrocarbons. Working Temperature Range: -30°C to 100°C. 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.
