STE124-055-014-025 is a t-duo manchet w/spring that works as double acting and can be used in piston applications. The material used on this t-duo manchet w/spring is made of NBR/METAL-SPRING 90 shore. The maximum allowed pressure is 60 BAR.
The dimensions has an inner diameter of 14 mm, an outer diameter of 55 mm and a height of 25 mm.
About the sealing profile STE124
STE124 Piston seals are designed as a double acting seal and produced by molding NBR with metal inserts. By using a spring which create pre-load on the sealing lips, the STE124 piston seals provides increased performance even under low pressures. They can be used in pneumatic applications too. Can be used safely up to 16 BAR in pneumatic applications and up to 60 BAR in hydraulic applications.
About the material NBR/METAL-SPRING
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. Furthermore, in this case, a metal spring is inserted which creates a preload on the sealing lips.
