Precautions for the use of deep groove ball bearings
For deep groove ball bearings, the bearing load is too small during operation, which will cause sliding between the ball and the raceway, which will become the cause of scratches. This is especially true for large deep groove ball bearings with heavy ball and cage weights. In many cases, bearings will corrode. There are many reasons for bearing corrosion. The most common factors in our daily life are the following:

The number of revolutions or hours that a bearing experiences before pitting occurs under a certain load is called the bearing life.

The main problems faced by China's bearing industry
According to the National Bureau of Statistics data, in 2011 China bearing manufacturing industry scale (annual sales revenue of more than 20 million yuan) a total of 1,416 enterprises, the annual industrial output value of 193.211 billion yuan, an increase of 27.59%; sales revenue of 191.097 billion yuan, an increase of 30.30%; total profit of 12.523 billion yuan, compared with the previous year's growth of 26.54%. It is expected that by 2015, China's bearing production is expected to exceed 28 billion sets, the main business income is expected to reach 210 billion yuan, becoming the world's largest bearing production and sales base.

The origin of the development of bearings
An early form of linear motion bearing was a row of wooden rods placed under a row of skids. Modern linear motion bearings use the same principle of operation, except that sometimes balls are used instead of rollers.

Prospects for the Use Prospects of Ceramic Bearings and Ceramic Ball Bearings
Ceramic bearings and ceramic ball bearings have many excellent properties such as: self-lubricating, high temperature resistance, corrosion resistance, anti-magnetic, electrical insulation, etc., yet to be developed and utilized in a wider field, and the potential application fields are huge. High-quality high-speed ceramic ball bearings: can serve the domestic machine tool industry well.

Features of spherical plain bearings
The structure of the spherical plain bearing is simpler than that of the rolling bearing, which is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Joint bearings are generally used for low-speed swinging motion (ie angular motion). Since the sliding surface is spherical, it can also perform tilting motion (ie self-aligning motion) within a certain angle range. When the degree is large, it can still work normally.
