OT04207012WC is an oil seal and can be used in rotary/axial moving applications. The material used on this oil seal is made of NBR/Carbon steel. The maximum allowed pressure is 0,5 BAR.
The dimensions has an inner diameter of 42 mm, an outer diameter of 70 mm and a height of 12 mm.
About the sealing profile OT-WC
The OT-WC profile's metal ring is not cast in NBR and is therefore exposed. An additional metal ring is also fitted, which gives the profile more rigidity. The advantage of this profile is that it can be used for particularly firm and precise positioning in the bore.
About the material NBR/Carbon steel
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 -40°C and +100°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. Carbon steel is a common type of steel that is an alloy of iron and carbon. It has a higher carbon content, lower melting point and greater durability compared to stainless steel. Carbon steel is the most widely used engineering and construction material for large-scale industrial applications, including marine structures, power plants, transportation, chemical processing, and oil production and refining.
