U-RING 95X110X10.5 NBR

STA181-095-110-010N 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 NBR 90 shore. The maximum allowed pressure is 160 BAR.

The dimensions has an inner diameter of 95 mm, an outer diameter of 110 mm and a height of 10.5 mm.

About the sealing profile STA181

STA181 sealing elements are produced with shorter inner lips to be used in rod applications. Its special profile enhances static sealing performance. Standard STA181 rod sealing elements are produced of NBR material and can be used under dirty and heavy conditions.

About the material NBR

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.
