The higher the importance of imported bearings, the more careful they need to be inspected

Rolling bearings use various mechanical equipment, and the increasingly stringent market requirements for imported bearings require equipment and other properties, resulting in increasingly diverse performance. To select the most suitable bearing from a large number of structures, sizes, and requires different angles. When choosing imported bearings, it is generally believed that the difficulty arrangement of installation and removal, the size of imported bearings, and the market for bearings, as well as the space allowed, generally determine the structure of imported bearings. Comparative research on the design lifespan of various machinery and the limitations of various durable imported bearings, while determining the bearing size. When choosing imported bearings, bearings often tend to believe that the lifespan of lubricating grease during aging, fatigue life of grease, wear resistance, and low noise also require thorough research.

In addition, according to different applications, it is necessary to choose bearings that are specially designed for precision, clearance, cage structure, lubricating grease, and other requirements. However, there is no specific order or rule when selecting bearings. Priority should be given to the conditions, performance, and related matters required for imported bearings, especially practicality. In order to maintain the original performance of bearings as intact as possible, maintenance should be prioritized to prevent accidents, ensure operational reliability, improve productivity, and be economical. Corresponding mechanical operation and maintenance standards, regular and optimal conditions. This includes monitoring the operating status, supplementing or replacing lubricants, and regularly inspecting and clearing them. As a maintenance operation issue, the rotational sound, vibration, temperature, lubrication conditions, etc. of imported bearings have been addressed.

Cleaning of bearings: Remove the bearings for repair, record the appearance of imported bearings for the first time, confirm the remaining amount of lubricant, sample and inspect the lubricant used, and clean the bearings. As a cleaning agent, gasoline and kerosene are generally used. Remove the bearing for cleaning, cleaning, and fine washing, and place it in a container with the first metal mesh bottom to prevent direct contact with the dirt of the imported bearing. Rough cleaning, if the bearing rotates with dirt and damages the rolling surface of the bearing, attention should be paid. In crude oil cleaning, use a brush to remove grease and viscous materials, generally clean, and wash into fines. Fine cleaning is the process of washing oil while carefully cleaning the bearings on one side while rotating. In addition, the cleaning oil must be kept clean

Maintenance and judgment of bearings: It is necessary to determine whether they can be used for cleaning, inspecting, and disassembling bearings. Check the raceway, raceway, surface condition, cage wear, customs clearance of imported bearings, and improvement in dimensional accuracy for any unrelated damage or abnormalities. Non separable small ball bearing, inner ring, supported horizontally with one hand, rotate outer ring to confirm smooth operation. The tapered roller bearing and other separable bearings can roll the body, and the surface of the outer ring raceway has been inspected. Large bearings, as they cannot be rotated by hand, should pay attention to checking the raceway, cage, and wall of the rolling element, such as appearance. The importance of higher imported bearings requires more careful inspection.
