  • STE104-065-053-020 is a double acting piston seal that works as double acting - 3 pieces and can be used in piston applications. The material used on this double acting piston seal is made of NBR/NBR-FABRIC/POM 80 shore. The maximum allowed pressure is 400 BAR.

    The dimensions has an inner diameter of 53 mm, an outer diameter of 65 mm and a height of 20.5 mm.

    About the sealing profile STE104

    Thanks to its fabric reinforcement with high mechanical strength, our STE104 compact seals has high abrasion resistance. STE104 compact seals, which does not stick on surfaces, consists of 3 pieces. With its long-life, our STE104 compact seals are ready for heavy duty applications.

    About the material NBR/NBR-FABRIC/POM

    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. NBR-fabric is a synthetic woven NBR material which enhances the durability of the seal. Polyacetal (POM) (Polyoxymethylene) materials are used as back-up rings or guidening element materials in hydraulic and pneumatic systems. There are two types of POM, filled with or without fibreglass, depending on their use. Despite working temperatures ranging from -40°C to +140°C, real dimensions can not remain stable in excess of 100°C. It can be used safely with mineral oils and HFA, HFB type oils. Types with added fibreglass provide longer lasting contact pressure resistance.
