The commonly used materials for oil seals are: nitrile rubber,
fluorine rubber, silicone rubber, acrylic rubber, polyurethane,
ptfe, etc.
Nitrile rubber (NBR)
It has good heat and wear resistance, resistance to all kinds of
lubriC.A.Ting oil, grease, oil and gas mixture, suitable for
temperature -30~120 degrees Celsius, but can not be used in
phosphate system hydraulic oil and gear oil containing extreme
pressure additives, in gasoline and low aniline point mineral oil
stable performance.
Polyacrylate rubber (ACM)
Excellent oil resistance, heat resistance, wear resistance, ozone
resistance, uv radiation resistance, especially resistance to
extreme pressure liquid agent lubriC.A.Ting oil, gear oil, motor
oil, oil, petroleum hydraulic oil, etc., suitable for -30~150
degrees Celsius range of work.
Fluorine rubber
Aging resistance, heat resistance, oil resistance, almost
applicable to all lubriC.A.Ting oil, fuel oil, gasoline, in the oil
containing extreme pressure additives is not easy to harden, but
cold resistance, high temperature wear resistance is poor,
permanent compression deformation is large, suitable for the
temperature of -20~250 degrees Celsius.
Silicone rubber
With outstanding high and low temperature resistance, can be used
at 150 degrees Celsius for a long time without performance change;
It can be continuously used for 10000h under 200 conditions, and it
can maintain its unique advantages of elasticity, ozone resistance
and weather resistance in the working temperature range of -70~260.
Polytetrafluoroethylene
It has outstanding chemical stability, thermal stability,
antifriction and self lubricity, and its cracking temperature is
above 400. Therefore, it can work in the temperature range of
-200~300 degrees Celsius. In addition to free fluorine and alkali
metals, it has excellent corrosion resistance to chemicals,
solvents, hydroxyl compounds and acids [2].
Nitrile rubber compared with fluorine rubber material is to use a
wide range of oil seal, the cost is low, but the heat resistance
and sealing has improved significantly, but the cost is higher, and
still have some adverse commonness of ordinary rubber materials,
such as poor wear resistance and short service life, particularly
sensitive response to the eccentric shaft, such as leakage
phenomenon is relatively common. PTFE oil seal is a product with
high technical content, which is the development direction of oil
seal in the future [2].
When choosing the material for the oil seal, the compatibility of
the material to the working medium, the adaptability to the working
temperature range and the ability of the lip edge to follow the
rotating axis at high speed must be considered. Generally, the
temperature of the lip edge of the oil seal is 20~50℃ higher than
the temperature of the working medium. Attention should be paid to
the selection of the oil seal material. The working range of the
oil seal is related to the material used in the oil seal: the
material is nitrile rubber (NBR) -40~120℃, Alic rubber (ACM)
-30~180℃, fluorine rubber (FPM) -25~300℃.
