U-RING 95X110.5X6.3

STA209-095-110-006 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 95 mm, an outer diameter of 110.5 mm and a height of 6.3 mm.

About the sealing profile STA209

STA209 Buffer seals are used as the first sealing element in hydraulic cylinders and rods. They consist of high performanced PU and POM support ring. STA209 Buffer seals must be combined with other sealing elements.

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.
