The bearing industry has developed rapidly in recent years. At the same time, the requirements for bearing precision are higher in various industries. In many cases, the requirements for bearing installation space are strict, and the requirements for bearing size and quality have reached a new height. In response to this situation, LRZ has developed a thin-walled ball bearing of equal section, which ranks among the best in the world in terms of process and technology.

Thin-walled ball bearings of equal section are also called flexible bearings. They have not appeared in China for a long time. There are only a few bearing companies in foreign countries. Compared with ordinary bearings, thin-walled bearings have light weight and thin walls. The small size is very suitable for occasions where the installation space is relatively strict, and has the superiority that ordinary bearings are incomparable. It is widely used in many industries such as aerospace, medical, instrument and robot. At the same time, because the thin-walled ball bearings of equal section are very thin and light, the production difficulty is relatively increased, which limits the rapid development of such bearings. At present, imported bearings are mainly used in China.

The development of such thin-walled ball bearings with equal cross-section, after years of hard work, the thin-walled ball bearings of equal section have become the LRZ company's fist products, a full range of thin-walled bearings, many types of models, large size range, in the first half of 2011 Has developed a maximum-section inner diameter of 40 inches (metric 1016mm) of equal-section thin-walled ball bearings, is currently the largest size of the same-section thin-walled ball bearings in the world, there are few companies in the world can produce, has begun mass production and export to Europe and the United States market . The mass production of large-size equal-section thin-walled ball bearings proves the company's strong product development and production capacity. It also shows that only the innovative R&D road is the domestic bearing industry going global.
