Bearings are a kind of commonly used mechanical hardware products. Good bearings need to have excellent sealing performance during use. At present, the seals of bearings can be divided into two types: self-contained sealing and external sealing. Generally, the self-contained sealing is relatively simple. The cost is also relatively low, and the bearing and sealing performance device is a sealing device with various properties inside the installation end cap. If the sealing performance is better, then some factors need to be considered in the sealing process.
The factors that need to be considered for bearing sealing are:
1. Bearing lubricant and type (grease and lubricating oil);
2, the working environment of the bearing, the size of the occupied space;
3. Advantages of the support structure of the shaft, allowing angular deviation;
4. The circumferential speed of the sealing surface;
5, the working temperature of the bearing;
6. Manufacturing costs.
According to the working conditions of the bearing and the working environment, the sealing degree is often used in engineering design to achieve a better sealing effect.

Clout Nails
Clout nails are a kind of large head Roofing Nails. Also known as shingle nails or felt nails. A clout is a relatively short, thick nail with a large, flat head used for attaching sheet material to wooden frames or sheet. A typical use is fixing roofing felt to the top of a shed. Clouts are also used in timber fence palings. They are usually made of galvanized mild steel, but copper clouts are also available.
