The so-called TIMKEN imported bearings plus sealing function equipment; is made inside the equipment end cover and other sealed equipment with various functions.
The following main factors should be considered for the selection of TIMKEN imported bearings and seals:
1. TIMKEN imported bearing smoothing agent and variety (smooth grease and smooth oil),
2. The working environment of TIMKEN imported bearings; 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. The operating temperature of TIMKEN imported bearings,
6. Making money.
The external seal is divided into two types: non-touch type and touch type. 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. The seal in this way; almost no conflict heat in the work; no wear; uniquely suitable for high speed And high temperature occasions. Non-touch seals are commonly used for voids; labyrinth and washers are not the same as the layout;
The gap of the non-touch seal is preferably as small as possible.
2) Touch-type sealed touch seal is a seal that seals its relative moving parts without gaps. This seal is directly touched by the seal and the cooperation piece; it has a large conflict in work; the heat is also large; easy to form Smoothness is bad; 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.; occasion.
According to the working condition of TIMKEN imported bearings and the working environment, the sealing degree is required; in engineering design, it is often used to apply various sealing methods to achieve better sealing effect.
