Precautions for shaft sleeve maintenance are as follows:

1 Check the wear of the shaft sleeve: Wear of the shaft sleeve can cause equipment to operate with damage, low production efficiency, accelerate equipment aging, and other hazards. Inspect the wear of the shaft sleeve to ensure that its wear does not exceed the rated range. For example, using Sore carbon nanopolymer materials, on-site repair can be achieved within 6-8 hours

2. Ensure accurate installation of the shaft sleeve: The shaft sleeve is part of the sliding bearing and is designed with a clearance fit manufacturing process with the shaft. When installing the shaft sleeve, ensure its position is accurate and stable to avoid interference or looseness, in order to avoid additional wear and damage to the shaft sleeve

3. Regular lubrication of shaft sleeve: Regularly lubricating the shaft sleeve can reduce friction and wear between the sleeve and the shaft, and improve the service life of the sleeve. Suitable lubricants should be selected based on the operating condition and usage environment of the shaft sleeve, and used and stored correctly

4. Regular inspection of bearings: The shaft sleeve is installed on the bearing, and regular inspection of the bearing's condition can avoid additional wear and damage to the shaft sleeve. Check the clearance, wear level, and sealing effect of the bearings to ensure their normal operation

5. Pay attention to the operating environment of the equipment: The operating environment of the shaft sleeve has a significant impact on its service life and performance. The working environment of the equipment should be kept clean and dry to avoid adverse factors such as overheating, undercooling, or excessive vibration

6. Pay attention to maintenance and replacement: When maintaining and replacing the shaft sleeve, it is necessary to strictly follow the operating procedures to ensure safety. Surface treatment, material blending and application, installation of shaft sleeves, curing, removal of excess materials, and reinstallation of components are required. Use the correct tools and equipment to avoid additional damage to the equipment
