NU330EM/C3J20C Bearing Installation and disassembly of insulated bearings 1. Bearing loading and unloading must pay attention to the following items: A. Use appropriate tools and handling methods B. Carefully avoid using bearings to cause strong impact on the bearings, resulting in scars and indentations on the bearings. Damage such as breakage affects bearing use. C. Keep the bearings and machines clean, and do not allow dust, moisture and other debris to enter the bearing. D, to prevent bearing corrosion, to avoid use in wet places, and in order not to sweat, should wear gloves, not allowed to contact the bearing. Immediately after assembly, the lubricant is applied to the bearing surface. Second, the installation of the bearing sequence is as follows: A. Cleaning the bearing and related components B. Check whether the size of the relevant parts is qualified C. Install the bearing D. Rotate the machine to check if there is any stuck or abnormal sound E. Add lubricant ★ Bearing storage A. Bearings are prohibited from being stored in the same warehouse as chemicals. B. The warehouse where the bearings are stored should be clean, dry, ventilated, and protected from harmful substances such as sour vapors. C. Under normal storage conditions, the effective rust-preventing period of the bearing is 12 months, more than 12 months, the bearing should be re-cleaned, coated with anti-rust oil and packaged. ★Maintenance method of bearing 1. Cleaning of bearing: When disassembling the bearing for inspection, first record the appearance of the bearing, confirm the residual amount of lubricant, and wash the bearing after sampling the lubricant for inspection. As a cleaning agent, a cleaning agent or kerosene is generally used. 2. The cleaning of the removed bearings is divided into coarse cleaning and fine cleaning. They are placed in the container respectively, and the metal mesh bottom is placed first so that the bearing does not directly contact the container. In rough cleaning, if the bearing is rotated with dirt, it 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. 3, fine washing, the bearing is rotated in the cleaning oil while carefully cleaning. In addition, the cleaning oil should always be kept clean. 4. Inspection and judgment of the bearing: In order to judge whether the removed bearing can be used, it should be checked after the bearing is cleaned. Check the raceway surface, the rolling surface, the state of the mating surface, the wear of the cage, the increase of the bearing clearance, and the damage and abnormality that are irrelevant in dimensional accuracy. For non-separable miniature ball bearings, use one hand to support the inner ring horizontally and rotate the outer ring to check if it is smooth. 5. Separate bearings such as tapered roller bearings can be inspected separately for the rolling surfaces of the rolling elements and the outer ring. 6, large bearings can not be rotated by hand, pay attention to check the appearance of rolling elements, raceway surface, cage, ribs, etc., the importance of the bearing is higher, the more careful inspection.
