Bearing seals can be divided into own seal and additional seal types. The so-called built-sealed bearing is to manufacture the bearing itself to have a sealing performance of the device. Such as bearings with dust cover, ring. This seal is very small footprint, easy installation and removal, the cost is relatively low.
The so-called external bearing sealing device that is installed inside the cover and other manufactured sealing means having various properties.
Additional bearing seal selection should consider the following several main factors:
1. The bearing lubricant and types (greases and oils);
2. The bearing work environment, the size of the space occupied;
3. The advantages of the support structure axis, allowing angular deviation;
4. The circumferential speed of the sealing surface;
5. bearing operating temperature;
6. the manufacturing cost.
According to the bearing operating conditions and the working environment on the sealing degree requirements in engineering design is often integrated use of various forms of seal, in order to achieve a better seal. |
