In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call. Details:/ For a long time, China's photovoltaic industry major equipment manufacturing is basically monopolized by foreign companies, China's photovoltaic industry's major production equipment is heavily dependent on imports, equipment prices are high, maintenance costs and other issues have been plaguing business development. The main reason for this difficult situation is directly related to the failure to achieve full localization of solar cell wafer production. The lack of domestic silicon wafer multi-wire cutting machine is its culprit! With the rapid development of the global photovoltaic market, the demand for polysilicon grows rapidly. The silicon wafer multi-wire saw is one of the major equipment necessary for the production of solar polysilicon wafers. It is an electromechanical product with advanced cutting-edge technologies. Localization and mass production cannot be realized, and China's photovoltaic industry will never be able to get rid of the current situation of relying on foreign technology imports. A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary Roller Bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter.Like all bearings, they are used to reduce the friction of a rotating surface.

The solar photovoltaic industry is considered to be one of the most promising new energy industries. For a new energy industry in which raw materials, production, technology, and markets are all in their own hands, there is no reason why the “12th Five-Year Plan†vigorously advocates energy-saving and environmentally friendly low carbon green today. In the second half of last year, many countries in Europe, including Germany and Spain, successively lowered their PV subsidy quotas, which brought many uncertainties to the global PV market. However, due to lower than the market psychological expectations, investor confidence increased, the global photovoltaic market demand, product prices continued to rise.
Nowadays, one kind of six national patents, of which four are core technology patents and YL-DQ-F2156 silicon wafer multi-wire saws with independent intellectual property rights, have been used to inject stimulants into the domestic PV industry in distress. It is reported that the overall technology of the product has reached the international advanced level, in which the tension control technology of the cutting line, the synchronous technology of the retractable line motor and the main motor are at the international advanced level. Therefore, with the new silicon wafer multi-wire cutting machine entering the mass production and sales stage, it marked a major breakthrough in the manufacture of domestic photovoltaic major equipment, filling the domestic gap, with landmark significance.
In the coming years, global demand for polysilicon in the global photovoltaic market will increase rapidly. The national support policies for the photovoltaic industry will be gradually introduced. With the rapid growth of market demand and the strong support of macro policies, the future potential of silicon wafer multi-wire saws is unlimited. It is recommended that the cutting machine industry enterprises increase the degree of concern for the silicon wafer multi-wire cutting machine, introduce and master related technologies as soon as possible, strengthen the awareness of independent innovation, and constantly improve product performance, and strive to realize the complete localization of major equipment manufacturing in the photovoltaic industry as soon as possible. It is conducive to the development of the new energy industry and the enterprise itself.

Compared to Ball Bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding structure.
Needle bearings are heavily used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least eight needle bearings (four in each U joint) and often more if it is particularly long, or operates on steep slopes.
