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.

implementing off, stop, and, turn, and optimized
Adjust the industrial structure to meet the market demand. Japanese bearing companies in restructuring, changing marketing strategies, changes blindly attacking advance and retreat. Its strategic features are: implementing off, stop, and, turn, and optimized. Expand the advantages of product markets, shrinking weak market. General Bearing to high-volume, low-cost reorientation; many varieties of small quantities of bearing products to the cell reorientation. Japanese enterprises attach importance to product development, the economy without borders premise, based on the global development strategy. Has introduced its own specialty products business, according to the user's needs upfront investment made before the host of new products to meet the requirements of the host, for which won the trust of consumers around the world.
Fourth, the Japanese bearing companies focus on manufacturing technology and process development. In the delegation visit the manufacturers, companies are highly automated production and online automatic detection. But on the production line, not all devices are the most advanced, and some still 1960s or 1970s equipment, but it can and production lines together, and be able to ensure product quality, thanks to the Japanese enterprises attach importance to production technologies. Most business delegation visited the production plant, but the technical development department has a strong development capability, the focus on new product development, but also focus on production technology and process development and innovation, thus ensuring product quality.
After that the delegation visited the following items for domestic enterprises learn production techniques:
1, the bearing and the Precision bearing assembly automatic grinding line technology.
2, bearing automatic line-line automatic clinical testing technology.
3, precision steel ball manufacturing process and testing technology.
4, heat treatment production line array technology material automatically.
5, ball bearings double end grinder, the outer sleeve grinding technology.
6, CBN abrasive use of technology.
