About the sealing profile STA154

STA154 U-ring rod seals have a shorter inner sealing lip and are only produced for rod applications. They ensure 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.

About the material PU

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.
