Product Description

    Oil seals are generally divided into monomer type and assembly type, and the assembly type is that the skeleton and lip material can be freely combined, and are generally used for special oil seals  .From the sealing function, characteristics, structure type, working state and sealing mechanism of the oil seal, it can be divided into a variety of forms and different names, but it is customary to call the rotary shaft lip seal ring oil seal, and the seal with static seal and dynamic seal (general reciprocating motion) is called seal.The representative form of the oil seal is TC oil seal, which is a double-lip oil seal with a self-tightening spring completely covered by rubber, and the oil seal is often referred to as this TC skeleton oil seal.
    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 resistance, wear resistance, resistance to various lubricating oils, greases, oil-air mixtures, etc., applicable temperature -30~120 degrees Celsius, but can not be used in phosphate ester hydraulic oil and gear oil containing extreme pressure additives, in gasoline and low aniline point mineral oilMedium and stable performance. [5]
Polyacrylate rubber (ACM)
Superior oil resistance, heat resistance, wear resistance, ozone resistance, ultraviolet radiation resistance, especially lubricating oil, gear oil, motor oil, engine oil, petroleum-based hydraulic oil containing extreme pressure agent, etc., suitable for -30~150 degrees Celsius range of work.
Viton
Aging resistance, heat resistance, oil resistance, suitable for almost all lubricating oil, fuel oil, gasoline, not easy to harden in oil containing extreme pressure additives, but cold resistance, high temperature wear resistance is poor, permanent compression deformation is large, suitable for temperature -20 ~ 250 degrees Celsius.
   Plain Single Lip B (SC)It is generally used for high-speed and low-speed rotating shafts and reciprocating motion to seal mineral oil and water and other media.Ordinary oil seal, sed iun the case of less dust and impurities, when the medium pressure is <0.05MPa, the maximum linear speed is 15m/s, and the reciprocating speed is <0.1m/s [3]  .Plain Double Lip FB (TC)In addition to the above-mentioned characteristics of S-type oil seals, they are also dustproof.Ordinary oil seal, with dustproof lip can be dustproof, and the medium pressure is < 0.05MPa, and the linear speed is ≤15m/s.Springless BVSpringless, single-lip inner encapsulated skeleton rubber oil seal.Generally, it is suitable for low-speed working conditions, and the sealing medium is lubricating ester. Linear speed≤ 6m/s.Exoskeleton single lip WSingle-lip exposed skeleton rubber oil seal with spring, thin waist, good follow-up and good rigidity.Ordinary oil seal, used in the case of less dust and impurities, resistant to medium pressure < 0.05MPa. The speed of the axis of rotation ≤ 15 m/s.Exoskeleton double lip FWExposed skeleton rubber oil seal with accessory lip, thin waist, good followership, high stiffness and good coaxiality.Ordinary oil seal, with dust-proof lip can be dust-proof, and the medium pressure is < 0.05MPa. Rotational speed≤ 15m/s.Fabricated single-lip FZThe oil seal of the outer skeleton is formed by the inner and outer skeleton assembly and piping, and has the characteristics of high installation accuracy, fast heat dissipation and heavy load.It is suitable for heavy load conditions under high temperature and high speed conditions, the medium pressure ≤ 0.05MPa, and the maximum linear speed ≤ 15m/s [3]  .One-way reflow type right-handed SR, left-handed DLThe diagonal ribs with angles are measured in the air of the lip, and the principle of fluid mechanics is used to produce a one-way pumping effect, which has a reflux effect.It is related to the rotation direction of the shaft, due to the reflux effect, the radial force is smaller than that of the ordinary oil seal, which reduces wear and heat generation, improves the service life, and is suitable for the occasion when the medium pressure is < 0.05MPa, and the speed is ≤ 20m/s   .Pressure-resistant type NYThe lips are short, the waist is short and thick, and it has a pressure-resistant effect, and the working pressure is ≤ 3MPa.It is suitable for the occasion when the medium pressure is ≤ 3MPa, and is suitable for the shaft end oil seal of the high-pressure pump, and the PV value is ≤8 under normal circumstances. The speed of the axis of rotation ≤ 15m/s .
silastic
It has outstanding high and low temperature resistance, can be used for a long time at 150 degrees Celsius without performance change, can be used continuously for 200h under 10000 temperatures, and can maintain its unique use elasticity and ozone resistance, weather resistance and other advantages in the working temperature range of -70~260.
polytetrafluoroethylene
It has outstanding chemical stability, thermal stability, friction reduction and self-lubrication, and its cracking temperature is above 400. Therefore, it is able to work normally 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, hydroxides and acids  .
Nitrile rubber and fluorine rubber materials are widely used oil seals, the former is low cost, but the temperature resistance and sealing have been significantly improved, but the cost is high, and still has some bad commonalities of ordinary rubber materials, such as poor wear resistance, short service life, particularly sensitive to the eccentric reaction of the shaft, etc., leakage is still relatively common. PTFE oil seal is a high-tech product, which is the direction of the future development of oil seal  .
When selecting the material of the oil seal, the compatibility of the material to the working medium, the adaptability to the operating temperature range, and the ability of the lip to follow the rotation shaft at high speed must be considered. Generally, the temperature of the lip of the oil seal is 20~50 °C higher than the temperature of the working medium, and attention should be paid to the selection of oil seal materials. The working range of the oil seal is related to the material used in the oil seal: -40~120 °C when the material is nitrile butadiene rubber (NBR), -30~180 °C when the material is Aggreko rubber (ACM), and -25~300 °C when the material is fluorine rubber (FPM).
