The reasonable use of high temperature oil seals needs to pay attention to these matters!

The oil seal is also known as the oil protection ring. It is irreplaceable in the rotating parts of the car. In order to use it more rationally, Changzhou Shaoding Seal recommends that you should pay attention to these matters when using the high temperature oil seal.​​

1. Shaft speed: high-temperature oil seals should use high-speed oil seals for high-speed shafts due to design and structural reasons, and low-speed oil seals for low-speed shafts. Low-speed oil seals cannot be used on high-speed shafts, and vice versa.

2. Ambient temperature: In the case of high operating temperature, polyacrylate or silicon, fluorine, and silicon fluorine rubber should be selected. And should try to lower the oil temperature in the tank. When the operating temperature is too low, cold-resistant rubber should be used.

3. Pressure: The general oil seal has poor pressure bearing capacity, and the oil seal will deform when the pressure is too large. Under the condition of excessive pressure, a pressure-resistant bearing ring or a reinforced pressure-resistant oil seal should be used.

4. The degree of eccentricity on the installation of the high-temperature oil seal: If the eccentricity of the oil seal and the shaft is too large, the sealing performance will be deteriorated, especially when the shaft speed is high. If the eccentricity is too large, a "W"-shaped oil seal can be used.

5. The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.

6. Note that there should be a certain amount of lubricating oil on the lip of the oil seal.

7. Pay special attention to prevent dust from immersing in the oil seal. Oil seals are classified according to the rotational speed of the shaft. Oil seals can be divided into low-speed oil seals (less than 6m/s) and high-speed oil seals (greater than 6m/s). According to the pressure level that the oil seal can withstand, it can be divided into normal pressure type oil seal and pressure type oil seal. According to the structure and sealing principle of the oil seal, it can be divided into standard oil seal and dynamic return oil seal. In addition, according to the material classification of the oil seal components, it can be divided into a skeleton type oil seal and a skeleton type oil seal, a spring type oil seal and a springless type oil seal.
