Bearing seals can be divided into self-contained seals and external seals. The so-called bearing self-contained seal is to manufacture the bearing itself into a device with sealing performance. Such as bearings with dust cover, sealing ring and so on. The sealing space is small, the installation and disassembly are convenient, and the cost is relatively low.
The so-called bearing-incorporated sealing performance device is manufactured into a sealing device having various properties inside the {TodayHot} such as the mounting end cap.
The choice of bearing seals should consider the following main factors:
1. Bearing lubricant and type (grease and lubricant);
2. The working environment of the bearing, the size of the occupied space;
3. The advantage of the support structure of the shaft allows angular deviation;
4. The circumferential speed of the sealing surface;
5. The working temperature of the bearing;
6. Manufacturing costs.
