STA855-025-035-007N is a pneumatic cushioning that works as single acting and can be used in rod applications. The material used on this pneumatic cushioning is made of NBR.
The dimensions has an inner diameter of 25 mm, an outer diameter of 35 mm and a height of 7.8/6.3 mm.
About the sealing profile STA855
STA855 pneumatic cushioning seals are used for slowing the cylinder down after fast movements. Their standard production is from PU material.
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.
