In order to make the bearing adhere to outstanding smooth conditions and normal working environment; give full play to the bearing function; extend the service life; it is necessary to have a suitable seal for the rolling bearing; to avoid leakage of the smoothing agent and dust, moisture or other dirt Intrusion. The seal of the bearing can be divided into two types: self-contained seal and external seal. The so-called bearing self-contained seal is to make the bearing itself into a sealing function device. For example, the bearing has a dust cover, a sealing ring, etc. This seal takes up space. Very.

1. Bearing smoothing agent and variety (smooth grease and smooth oil),
2. Bearing working environment; occupying a large space.
3. The support layout of the shaft is strong; the viewpoint error is allowed,
4. The circumferential speed of the sealing surface,
5. Bearing operating temperature,
6. Production costs. Plus seals are divided into non-touch and touch types. The description is as follows:
1) Non-touch seal Non-touch seal is the seal that does not touch the parts with its relative movement; and the seal with proper clearance. This type of seal; almost no conflict heat in the operation; no wear; uniquely suitable for high speed And high temperature occasions. Non-touch seals are commonly used for void type; labyrinth and washer type, etc.; different applications are not used. Non-touch seals are preferably as small as possible. 2) Touch Sealed touch seal is a seal that seals with its relatively moving parts and has no gaps. This seal is directly touched by the seal and the cooperative part; it has a large conflict in the operation; the heat is also large; it is easy to form smooth and poor; The touch surface is easily worn; then the sealing effect and function are reduced. Therefore, it is only suitable for medium and low speed working conditions. Touch seals are commonly used in the form of felt seals, cup seals, etc.; Bearing operation conditions and working environment requirements for sealing degree; engineering design often uses a variety of sealing methods to achieve better sealing use.
