In the category of machinery industry, the domestic liquid flowmeter industry is not growing at a high rate. The growth rate in the past four years is between 21% and 26%. However, in the entire electromechanical industry, the liquid flowmeter industry still belongs to the progress of restructuring and transformation. Fast industry. Some middle and low-end products have scale advantages and international market competitiveness. For example, ordinary digital multimeters and other products account for a large amount of production in the world, and home electric meter capacity accounts for 45% of the world's total. At present, China has become gradually become export meter, microscopes, telescopes, thermometers, pressure gauges, water meters, gas meters, optical components and other products and exporting countries, high-end products such as container inspection equipment also began to make a breakthrough. At present, the liquid flow meter industry is a sector that directly competes with foreign companies. Foreign capital has entered the third phase in China. The stage is mainly joint ventures and technology exports. The joint ventures before and after the 1990s were converted into holdings as the primary stage, and now they have entered the intermediate stage of sole ownership and merger of outstanding Chinese enterprises. A ball bearing is a type of Rolling-Element Bearing that uses balls to maintain the separation between the bearing races.

China's liquid flowmeter industry still has some concerns. First of all, China is a developing country, and the liquid flowmeter industry has a gap of 10 to 15 years compared with developed countries. However, in the developing countries, China is a country with a large complete liquid flow meter industry and a strong overall strength.

Secondly, the demand for liquid flowmeters in China is very large, and it is one of the countries with rapid development. The growth rate of liquid flowmeters in the world is 3% to 4%. China has achieved an annual growth rate of more than 20% for four consecutive years, and some products already account for one-tenth of the world's total.
The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least three races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.
Ball Bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.
