What are the seals of bearings?
2022-08-26
Bearing seals can be divided into two types: self-contained seals and external seals. The so-called bearing self-sealing is to manufacture the bearing itself into a device with sealing performance. Such as bearing with dust cover, sealing ring and so on. This kind of seal takes up little space, is easy to install and disassemble, and has a relatively low cost.
The so-called bearing additional sealing performance device is a sealing device with various performances manufactured inside the installation end cover, etc.
The following main factors should be considered in the selection of bearing seals:
1. Bearing lubricants and types (grease and lubricating oil);
2. The working environment of the bearing and the size of the space occupied;
3. Advantages of shaft support structure, allowable angle deviation;
4. The peripheral speed of the sealing surface;
5. The working temperature of the bearing;
6. Manufacturing costs.
According to the working conditions of the bearing and the requirements of the working environment for the degree of sealing, various sealing forms are often used comprehensively in engineering design to achieve better sealing effect.
The bearings we produce are mainly used for: automobile parts, motorcycle parts, textile machinery, packaging machinery, food machinery, other machinery, etc
