 　　Due to the unique nature of the work environment, oil seals have higher requirements in terms of sealing performance, temperature resistance, wear resistance, and pressure resistance to ensure their adaptability to different work environments. Therefore, oil seal products should have higher requirements in terms of appearance and materials to ensure their quality. A good oil seal product is not only reflected in its performance, but also in its packaging, quality inspection, and after-sales service. Therefore, to make a good oil seal, these points must be addressed. 　　To address these issues, the NQKSF factory does the following: 　　Independent production of oil seal metal shells: To ensure strong compressive ability, the metal framework must be thick enough to support the entire oil seal and ensure its service life. The company produces its own oil seal metal shells. Our shells are treated rigorously to prevent rust and increase adhesion. They are soaked multiple ti...

　　As a manufacturer of oil seal products, we understand the importance of meeting high standards for sealing performance, temperature resistance, wear resistance, and pressure resistance in specialized working environments. This is necessary to ensure that our products are adaptable to different working conditions. Therefore, both the appearance and material of our oil seals require higher specifications. A good oil seal product should not only exhibit outstanding performance, but also include quality packaging, strict quality control, and excellent after-sales service. To achieve these goals, our factory takes the following steps: 　　High-quality raw materials 　　The performance of an oil seal depends on the quality of its raw materials. We only use top-quality materials, including NBR, FKM, hydrogenated nitrile rubber, and silicone rubber, which are all imported. 　　Advanced vulcanization technology 　　Our vulcanization technology is highly advanced. We use mature and soph...

 　　PU oil seals, also known as polyurethane oil seals, are a type of sealing device used to prevent the leakage of oil or other fluids from machinery. This type of seal is commonly used in automotive and industrial applications, where there is a need for a reliable and durable sealing solution. 　　PU oil seals are made from a special type of polymer called polyurethane, which is known for its excellent mechanical properties and resistance to abrasion, tearing, and chemicals. The material is also capable of maintaining its shape and sealing properties over a wide range of temperatures, making it ideal for use in harsh environments. 　　One of the key advantages of PU oil seals is their ability to resist wear and tear caused by friction and exposure to oil or other fluids. This helps to extend the lifespan of the machinery and reduce the need for frequent maintenance or replacement of the seals. Additionally, PU oil seals are resistant to water, dust, and other contaminants...

 　　Floating oil seal, also known as a mechanical face seal, is a specialized sealing device used to prevent the leakage of oil or other fluids from machinery. This type of seal is commonly used in heavy machinery such as construction equipment, industrial machinery, and marine vessels. 　　The floating oil seal consists of two main components: the seal ring and the mating ring. The seal ring is a flexible component that is designed to move with the shaft and maintain contact with the mating ring, which is a stationary component that is mounted on the housing. The seal ring is typically made of a durable rubber or elastomeric material, while the mating ring is made of a harder advantage of a floating oil seal is that it can accommodate axial and radial movements of the shaft without affecting the seal ring is designed to float or move along the shaft, allowing it to maintain a constantring. This helps to prevent fluid leakage and extends the lifespan of the machinery by r...

 　　Radial shaft seal rings are ready-to-fit seals for sealing rotating shafts. They consist of an outer elastomer casing and a reinforcement ring located inside. The tension spring provides compression pressure of the sealing lip on the reinforced shaft and contributes to sealing in static areas. 　　Form A: single lip, model conforming to standard DIN 3760 (ISO 6194/1) smooth outside diameter. 　　Form AS: double lip, model according to DIN 3760 (ISO 6194/0) smooth outside diameter, with dust lip for protection against impurities from the outside. 　　The NBR material has high wear resistance and is resistant to fuels, oils, hydraulic oils and greases. 　　Usage limits: 　　Circumferential speed (m/s): ≤12 　　Pressure (MPa/bar): ≤0.05/0.5 (radial shaft seal rings are generally designed for use at atmospheric pressure). 　　Temperature range : 　　-40°C up to +100°C. 　　Tolerances: 　　Accommodation : 　　Recommended tolerance H8. 　　Surface roughness Ra 1.6 to 6.3 μm.

 　　O-rings are sealing elements providing a seal against liquid and gaseous media. They are suitable for secondary static and dynamic use. O-rings can be integrally sealed radially or axially. Sealing is created during assembly by axial or radial compression of the section. In working condition, the fluid pressure increases the deformation of the O-ring and therefore strengthens the sealing function. For optimal sealing, choose O-rings with the largest possible torus diameter. 　　In the assembly space, pay particular attention to the following elements: groove filling, precompression, elongation and settlement. 　　During static use, the precompression should be between 15 and 30% of the torus diameter. During dynamic use, it should be between 10 and 18% (hydraulic) or between 4 and 12% (pneumatic). 　　When fitted, the O-ring must be: 　　- expanded by max. 6% of inside diameter 　　- tablet of max. 3% of inside diameter. 　　The NBR material has high wear resistance and is re...

 　　Oil seal is mainly used to seal media with pressure. It has advantages when sealing low viscosity and gaseous media. 　　TC type oil seal is double lip (one main lip and one auxiliary lip), one spring, and the steel framework is completely wrapped by rubber. It is used in the situation of low pressure, one side has sealing medium and the other side has slight dust. The maximum pressure is 0.03mpa (0.3kgf / cm2). 　　Nitrile rubber, with a service temperature of minus 40 ° to 125 °, is resistant to mineral oil and has good wear resistance. It is most used in oil seals, but it cannot be used in ketone and lipid polar solvents. 　　There are more than 5000 models of nitrile rubber, with sufficient inventory.
