Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.

ZWZ precision bearings production line
There is no doubt that for a long time, domestic major equipment supporting high-grade Precision bearing most dependent on imports, and subject to the restrictions abroad, to a certain extent, restricted the development of China's equipment manufacturing industry, and some other accessories bearing a national major equipment the bottleneck.
2005, ZWZ generous launched precision technology and manufacturing industrial park construction, the implementation of a total investment of up to 14 billion "sixteen key areas of major technical equipment, bearings supporting the transformation projects." After completion of the project to increase the international first-class equipment, the implementation of world-class manufacturing technology and modern logistics facilities, station equipment, etc., to form a high level large, sophisticated, high-speed, high-performance products bearing the special structure of manufacturing capabilities, and built the only key technical R & D laboratory equipped with special bearing base.Wazhou first set of high-precision exports to Europe wind wheel bearings sent to the user; medical equipment for mass production of the new wheel bearing capacity; has a world-class high-tech precision machine tool bearings produced ...... smoothly. In recent years, ZWZ to develop two kinds of new products every day of the rapid increase in species, a total of more than 4,000 kinds of new product development, the transformation of the old 1200 kinds of products, 1,200 kinds of import substitution, export expansion 1300 kinds of products, the application of defense and high precision advanced the field of more than 200 kinds of products, there are more than 400 kinds of product specifications for wind power generation, precision mill, CNC machine tools, construction machinery and other major national technology and special ....... Today, ZWZ bearing industry has been ranked ninth in the world,
