High pressure oil seal

High pressure oil seal

Oil seal characteristics1. Structural type I has a small lip pressure area and can maintain its rigidity, suitable for use under small diameter and medium pressure.2. Structural type II has small lip deformation under pressure, and the skeleton is designed for overall pressure resistance, suitable for use under large diameters and high pressures.3. The lip of structural type III adopts an optimized structural design, and the slanted lip design allows the oil seal to adapt to a relatively high PV value: under a pressure of 200 kilograms, the rotational speed is required to be above 0.75 meters/second.Advantages of oil seals1. The rubber joint has good static pressure2. Reliable and optimized pressure bearing design3. Can withstand high temperatures (based on rubber material)4. The lip of the oil return line design has better sealing performance

Cassette Oil seal

Product IntroductionCassette Oil seal are developed to meet the needs of long service life, high functional reliability, environmental protection, simple handling, and low price of seals. Cassette Oil seal are a complete system that integrates multiple seals, serving as oil seals, wear sleeves, and dust protection within a unit, eliminating the need for additional components such as shaft sleeves or dust protection. This design has made significant improvements in its ability to isolate water, dirt, and dust for extended periods of time. It has a higher ability to withstand eccentricity, high pressure, and misalignment than radial seals.Product FeaturesDesign: Patent DesignOuter edge of oil seal: metal frameworkThe sealing lip is equipped with a springEquipped with dust lipHigh resistance to pollutant invasionSolved the problem of secure assemblyProduct Advantages1. Can extend the maintenance cycle of components2. The surface of the sealing shaft does not need to be hardened or ground3. When the old method cannot solve it, a Cassette Oil seal can generally be used to solve it, and there is no need to change the cavityWhen maintaining or replacing oil seals, the shaft surface does not need to be machined again

Gas Spring oil seal A

Gas Spring oil seal A

Product IntroductionThe upper limit of Gas Spring is required to have a pressure of 20 MPa. The oil seal maintains the pressure through the sealing medium to realize the function of Gas Spring; Advantages of Sealdo Gas Spring oil seal:1. Good high and low pressure sealing retention2. Lower starting resistance3. Lower dynamic and static friction

Tetrafluoro oil seal

Product IntroductionRubber coated activated oil seal is a single skeleton outer rubber oil seal that is formed directly without the need for an inner skeleton, after the PTFE lip is activated and thermally vulcanized onto the rubber.Its notable feature is that compared to the double skeleton oil seal, the lip surface treatment is more wear-resistant.After vulcanization, it forms a whole, preventing leakage between the lip and the skeleton; Greatly improve sealing performance.

Material composition of automotive oil seals

Material composition of automotive oil seals

The commonly used rubber material for automotive oil seals is nitrile rubber. Nitrile rubber is currently a commonly used rubber material due to its low cost and wide range of applications. In the daily manufacturing of oil seals, different rubber materials are selected based on the sealing medium (usage environment or occasion), usually including silicone rubber, fluorine rubber, polytetrafluoroethylene, polypropylene ester rubber, and so on.1. Nitrile rubberNitrile butadiene rubber (made by lotion polymerization of butadiene and acrylonitrile) has poor cold resistance and relatively good heat resistance; The wear resistance increases with the increase of acrylonitrile content, with good water resistance and oil resistance, making it a widely used rubber in the sealing industry.2. Silicone rubberSilicone rubber has excellent weather resistance, extremely poor alkali resistance, weak wear resistance, and low tensile strength, so it is generally not used for dynamic sealing; Its high-temperature resistance is only lower than that of fluororubber, but its low-temperature resistance is among the best among rubber materials.3. Fluorine rubberFluorine rubber has good oil resistance and poor cold resistance. Fluorine rubber is a stable and balanced rubber among all rubbers, and is also a good high-temperature resistant rubber in the rubber industry, with relatively high prices; Good wear resistance, suitable for dynamic sealing environments.4. Acrylate rubberAcrylate rubber has excellent oil resistance at high temperatures, but poor cold resistance and water resistance; The wear resistance is not as good as polyurethane rubber; Stable performance in lubricating oils containing phosphorus, sulfur, and chlorine additives.5. Butyl rubberButyl rubber has good weather resistance, but is extremely resistant to water, ozone, and chemical corrosion; Self adhesion and mutual adhesion are poor, and compatibility is also poor. It is not suitable to use the same material together, and can only be used together with ethylene propylene rubber and polyethylene.6. Ethylene propylene rubberThe aging resistance of ethylene propylene rubber is good, and its weather resistance and water resistance are also very good, with extremely high chemical stability, but its oil resistance is also very poor, as well as the self adhesion and mutual adhesion of butyl rubber.7. PolytetrafluoroethylenePTFE has strong acid and alkali resistance, good antioxidant performance, high temperature and low temperature resistance, and excellent weather resistance; In solid materials, its friction coefficient is low, surface tension is small, resulting in high lubrication and strong non adhesion. But its radiation resistance is poor, and it will degrade after being subjected to high-energy radiation, and its elasticity is worse than other rubbers.Due to the different specifications of automotive oil seals produced by each manufacturer, as well as the different materials and processing accuracy required by customers, Sealdo Technologies Corporation can conduct comprehensive calculations on rubber and plastic seal products according to customers' different needs and make a quotation for customers. We welcome everyone to consult with automotive oil seals.
