What are the uses of rolling bearings? Rolling bearing is a relatively precise mechanical component, which is mainly used to reduce the loss caused by friction between the shaft and the shaft during the operation. Rolling bearings can well support the normal operation of the shaft and the parts between the shafts during the rotation process, and can also keep the shaft in a normal working position, thereby improving the accuracy of rotation during operation. Of course, if the rolling bearing encounters some faults during use, it will be very convenient to maintain, and at the same time, the reliability of the work will be improved. Secondly, the starting performance of the rolling bearing can also be good, and it can maintain a relatively high load capacity at medium speeds. However, compared with the sliding bearing, the radial size of this product is relatively large, so the shock absorption capacity may not be particularly good, and when running at high speed, the life will be reduced, and it will also produce a larger sound. In addition, rolling bearings can well reduce the loss caused by friction, and further improve labor efficiency by reducing people's workload. In daily work, rolling bearings are used in many occasions.
