The key role of oil seals and introduction to common models

As one of the vital components in mechanical equipment, oil seals are mainly used to prevent liquids (such as lubricating oil) from leaking from between the rotating shafts, bearings or other moving parts of the machine, and to prevent contaminants (such as dust or moisture) from entering the machine. . Different models of oil seals have their own characteristics and are suitable for different application scenarios. This article will introduce several common oil seal models to help understand their importance in industry, home appliances and other fields.

1. 1.1×4 oil seal

The 1.1×4 oil seal is an oil seal based on the inch standard, where 1.1 inches represents the inner diameter and 4 inches represents the outer diameter. This type of oil seal is often used in applications such as automobiles and mechanical equipment. Because of its moderate size, it can provide good sealing effects for medium-sized equipment. The specific materials used may be selected according to different working environments, such as common nitrile rubber (NBR) or fluorine rubber (Viton), to cope with different temperatures and chemical substances.

2. AE2048H oil seal

AE2048H oil seal is mostly used in high temperature and high pressure environments, and is commonly used in automobile engines, hydraulic systems and other fields. Its dimensions are 20 mm inner diameter and 48 mm outer diameter, and the “H” at the end may represent that its material is hydrogenated nitrile butadiene rubber (HNBR), a material with high oil resistance and high temperature resistance. AE2048H oil seal can maintain good sealing performance for a long time under harsh working conditions and extend the service life of the equipment.

3. F6155 oil seal

F6155 oil seal is a manufacturer-specific product number typically used on a variety of industrial machinery or heavy equipment. The size and material of this oil seal need to refer to the specific manufacturer’s catalog. It is often used in high-load or harsh environments. Specific performance characteristics may include higher pressure and wear resistance.

4. TCM 26444 oil seal

TCM is a well-known oil seal brand, and 26444 represents a specific size or series. TCM’s oil seal products are widely used in automobiles, heavy machinery and other industries, with excellent sealing performance and durability. Its products use high-quality rubber materials, which can effectively prevent oil leakage and dust from entering, ensuring the normal operation of the machinery.

5. 3173 oil seal

3173 oil seal is also a typical manufacturer number, often used in environments that require high precision sealing. This type of oil seal is usually used in hydraulic equipment and precision machinery and can withstand high pressure and frequent operation to ensure the stability and safety of the equipment.

6. Electrolux oil seal

Electrolux is a well-known home appliance brand, and Electrolux oil seals are usually used in its home appliances, such as washing machines, vacuum cleaners, etc. This type of oil seal must have high water resistance and wear resistance to cope with the high humidity environment and long-term operation in home appliances. Due to the diversification of Electrolux equipment, the specifications and materials of its oil seals are also different. It is necessary to select the appropriate product according to the specific model.

7. M92074 oil seal

M92074 oil seal is generally used in heavy equipment, automobiles or other large machinery. This kind of oil seal has high mechanical strength and can work for a long time in harsh environments. The size and materials need to be confirmed specifically through the manufacturer’s catalog, but they are mostly used in high-strength and high-temperature environments.

8. BAHD oil seal CFW

BAHD oil seals are part of the **CFW (now Freudenberg) brand. CFW is a world-renowned seal manufacturer whose products are widely used in various industrial applications. BAHD series oil seals may have special designs and are suitable for high-speed rotation, extreme temperatures and complex chemical environments. CFW’s product quality and performance are well recognized, especially in applications requiring high precision and durability.

Summarize

There are many types and models of oil seals, from standard size 1.1×4 oil seals, to Electrolux oil seals for appliances, to application-specific TCM 26444 or BAHD oil seals, each with its own unique design and application needs. Choosing a suitable oil seal should not only consider its size, but also pay attention to its material and applicable working environment to ensure optimal performance and long-term operation of the equipment.
