In summary, the purpose of the deep groove type of ball races in a ball bearing is to enable the bearing to support radial and axial loads, reduce friction, facilitate smooth rotation, distribute loads evenly, and contribute to the overall efficiency and reliability of the bearing in various mechanical applications.

The expo was held in Shijiazhuang from July 29 to 31, leading equipment manufacturing enterprises from all over the country have appeared in the exhibition, Linxi County enterprise representatives - micro bearing, Zhongwei Zhuote hydraulic and other 17 enterprise representatives participated in the exhibition. Only on the morning of the opening ceremony, 17 exhibitors have signed 34 ordering contracts and reached 152 purchase intentions, which has achieved good results and further enhanced the popularity of Linxi Bearing.

In summary, the angle of contact in angular contact ball bearings is a fundamental design feature that enables the bearing to support combined radial and axial loads, accommodate high-speed operation, and provide high precision and rigidity in various industrial applications.

   - Cylindrical Roller Bearings: Cylindrical roller bearings are used in applications where high radial load-carrying capacity, rigidity, and precision are essential. They are employed in machine tool spindles, electric motors, and industrial equipment where heavy loads and precise motion control are critical.
