  • STA153-160-170-012P is a u-ring that works as single acting and can be used in rod applications. The material used on this u-ring is made of PU/POM 92 shore. The maximum allowed pressure is 400 BAR.

    The dimensions has an inner diameter of 160 mm, an outer diameter of 170 mm and a height of 12 mm.

    About the sealing profile STA153

    STA153 U-ring rod seals have shorter inner sealing lips and are only produced for rod applications. They leave lower oil film thickness due to the their second dynamic sealing lip. At the same time, they prevent the entry of unfavourable particles into the cylinder. The POM back-up ring offer high resistance to extrusion.

    About the material PU/POM

    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. 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.
