OIL SEAL 40X55X8 NBR W/DUST LIP

OTS04005508 is an oil seal and can be used in rotary/axial moving applications. The material used on this oil seal is made of NBR 70 shore. The maximum allowed pressure is 0,5 BAR.

The dimensions has an inner diameter of 40 mm, an outer diameter of 55 mm and a height of 8 mm.

About the sealing profile OTS

The OTS profile has a metal ring in the core of the oil seal which provides stability. This type of profile also has an additional dust lip which helps keep dirt and dust out. The outer part is typically molded from NBR, but is also available in many other materials. In most applications, oil seals are used to provide a seal for oil, grease or water against rotating parts.

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 -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.
