ROD SEAL 45X60.1X6.3 PU/NBR

STA159-045-060-006 is a rod seal that works as single acting and can be used in rod applications. The material used on this rod seal is made of NBR 98/70 shore. The maximum allowed pressure is 500 BAR.

The dimensions has an inner diameter of 45 mm, an outer diameter of 60.1 mm and a height of 6.3 mm.

About the sealing profile STA159

STA159 rod seals are composed of a high performance PU and a NBR O-Ring. They are designed as an alternative for seals made of PTFE materials. Advantages over PTFE products: No need of special assembly apparatus or conical sleeves during assembly. Compared with PTFE seals, extremely high price advantage. Higher extrusion resistance. Better sealing behaviour. Higher pressure resistance.

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.
