Support Center Bearing 74 20 876 232 / 20876232 for Renault 55mm

Bearing material-characteristics of bearing steel:

1. Contact fatigue strength
2. Wear resistance
3. Hardness
4. Anti-rust performance
5. Processing performance

In addition to the above-mentioned basic requirements, bearing steel should also meet the requirements of proper chemical composition, average external structure, less non-metallic impurities, external appearance defects conforming to specifications, and external surface decarburization layer not exceeding the regular concentration.

The selection of bearing seals should consider the following main factors:

1. Bearing lubricant and type (grease and lubricant);

2. The working environment of the bearing and the size of the space occupied;

3. Advantages of shaft support structure, allow angle deviation;

4. The circumferential speed of the sealing surface;

5. The working temperature of the bearing;

6. Manufacturing cost.

The sealing of the bearing can be divided into two types: self-sealing and external sealing. The so-called bearing with its own seal is to make the bearing itself into a device with sealing performance. Such as bearings with dust cover, sealing ring, etc. This kind of seal occupies a small space, is convenient to install and disassemble, and the cost is relatively low. The so-called bearing external sealing performance device is a sealing device with various performances manufactured inside the installation end cover. Bearing external seal is divided into non-contact seal and contact seal. Among them, the non-contact seal is suitable for high-speed and high-temperature occasions, and has different structures such as gap type, labyrinth type and gasket type. Contact seal is suitable for medium and low speed working conditions, and commonly used structural forms such as felt seal and cup seal.
