Bearings are very important components in mechanical engineering and various industrial applications. Sliding bearings and rolling bearings, as the two main types of mechanical transmissions, have their own advantages and disadvantages. So, who is the better choice for your equipment?

First, let's understand the basic concepts and main differences between rolling and plain bearings. Rolling bearings reduce friction through rolling elements (such as balls or rollers) and are suitable for high-speed, low-load scenarios. Sliding bearings, on the other hand, reduce friction by forming an oil film between the shaft and the bearing through lubricants, and are suitable for low-speed, high-load scenarios. For different problems and application scenarios, let's analyze them specifically:丨High speed application丨Recommended to choose rolling bearings. Due to the lower coefficient of friction of rolling bearings, the running speed is higher, for example, applied in motors or fans. In the selection process, first determine the shaft diameter, load and speed, and then select the appropriate model according to the catalog or engineering manual. This will maximize the advantages of rolling bearings, efficient operation and reduce energy consumption and wear. High load, low speed applications are recommended to choose plain bearings. Sliding bearings perform more stably under high loads and can better withstand shocks and vibrations. When selecting a bearing, first determine the shaft diameter, load and rotational speed, then select the appropriate lubricant, such as mineral or synthetic oil, and determine the oil film thickness according to the nature of the lubricant. This maximizes the advantages of plain bearings, extends equipment life and reduces maintenance frequency. 

In summary, bearing selection must be based on the specific application scenario. While rolling bearings excel in many situations, plain bearings also offer irreplaceable advantages under high loads and special working conditions. Understanding this key characteristic can help us make better decisions and improve the efficiency of equipment operation.
