Do you know what are the main functions of bearings? In fact, the functions of various types of bearings are different. We use bearing products in many places. As our machinery becomes more and more sophisticated, the market for bearings will develop better. The role of the bearing: Thrust ball bearings are separable bearings and can only bear axial loads. One-way bearings can only bear axial loads in one direction, and two-way bearings can bear alternating axial loads in two directions. Each ring of the deep groove ball bearing has a radial ball bearing with a continuous groove raceway whose cross section is about one-third of the circumference of the ball, which is suitable for precision instruments and so on. There are still many bearings on the market. Different bearings have different functions. Now, our technology is more and more developed, and the development of machinery is inseparable from bearings. When buying sliding bearings, we must pay attention to distinguish the quality of the bearings. When using the bearings, we must pay attention to maintenance, especially for products such as sliding bearings, which should be frequently lubricated for better use.
