In order to judge whether the removed imported bearings can be reused, check the bearings after cleaning. Carefully check the raceway surface, the rolling surface, the state of the mating surface, the wear of the cage, the increase in the clearance of the imported bearing, and the presence or absence of damage to the dimensional accuracy. Inspection and cleaning of the imported bearings of RY air-cooled centrifugal hot oil pump In order to judge whether the removed imported bearings can be reused, check the bearings after cleaning. Carefully check the raceway surface, the rolling surface, the state of the mating surface, the wear of the cage, the increase in the clearance of the imported bearing, and the presence or absence of damage to the dimensional accuracy. For non-separable miniature ball bearings, use one hand to support the inner ring and horizontally rotate the outer ring to check if it is smooth. Separate bearings such as tapered roller bearings can be inspected separately for the rolling surfaces of the rolling elements and the outer ring.

Large bearings cannot be rotated by hand. Pay attention to the appearance of rolling elements, raceways, cages, ribs, etc. The higher the importance of bearings, the more careful inspection is required.
Whether it can be reused or not, the RY air-cooled centrifugal hot oil pump is determined in consideration of the degree of damage to the imported bearings, mechanical properties, importance, operating conditions, and the period until the next inspection. However, if you have the following defects, you can no longer use them. New bearings must be replaced. There is a crack or a gap in any of the inner ring, the outer ring, the rolling element, and the cage. There is a break in any of the ferrule and the rolling element. There is significant slack in the raceway, ribs and rolling elements. There is rust and damage on the raceway surface and the rolling elements. There are severe indentations and marks on the raceway surface and rolling elements. The inner diameter of the inner ring or the outer diameter of the outer ring has obvious creep. The discoloration caused by heat is obvious. Bearings sealed with grease, seals, or dust caps are damaged. Botou Taibang Pump & Valve Manufacturing Co., Ltd. When cleaning and disassembling the imported bearings under the inspection of bearings, first record the appearance of the bearings, confirm the residual amount of lubricant, and after sampling the lubricant for inspection, wash the bearings. As a cleaning agent, gasoline and kerosene are commonly used. The cleaning of the removed bearings is divided into coarse cleaning and fine fine washing. In the container, the metal mesh bottom is placed first, so that the bearing does not directly contact the container. In the case of fine cleaning, if the bearing is rotated with dirt, the RY air-cooled centrifugal hot oil pump will damage the rolling surface of the bearing and should be noted. In the rough cleaning oil, use a brush to remove the grease and the adhesive. After it is almost clean, it is transferred to the fine wash.
Fine washing is to carefully clean the imported bearings while rotating in the cleaning oil. In addition, the cleaning oil should always be kept clean.
