Bearing seal can be divided into two categories, own seal and seal. The so-called bearing with seal is made bearing itself into a sealing device. Such as bearing with dust cover, sealing ring, etc. This seal take up the space is small, easy installation and disassembly, cost is low.

Alleged bearing and sealing device, it is inside the installation end cover manufacturing into a sealing device has a variety of performance.

The choice of bearing and seal should consider the following several major factors:

1. Bearing lubricant and types (grease and lubricating oil);

2. The size of the bearing work environment, take up the space;

3. Shaft supporting structure advantages, allowing the angular deviation;

4. The circumference of the sealing surface speed;

5. The working temperature of bearing;

6. The manufacturing cost.

According to the bearing working condition and working environment requirement for sealing on the engineering design is often integrated use of various seal form, in order to achieve better sealing effect.
