How to prevent deep groove ball bearing clearance change failure?

Preventing bearing clearance change failure requires a series of measures, covering aspects such as bearing selection, use, maintenance, and lubrication.

1. Select appropriate bearings: When choosing deep groove ball bearings, consider their type, size, material, and accuracy class to ensure they can meet the working requirements and load conditions of the equipment. At the same time, pay attention to the bearing clearance and fit requirements, and avoid choosing a fit that is too tight or too loose.

2. Correct installation and disassembly: When installing and disassembling bearings, follow the correct operating procedures and use appropriate tools and methods to avoid damaging or deforming the bearings. During installation, ensure that the bearing clearance meets the design requirements, and avoid excessive or insufficient interference.

3. Keep clean and dry: Deep groove ball bearings should always be kept clean and dry during operation to prevent contaminants such as dust, impurities, and moisture from entering the bearing interior. To this end, measures such as dust prevention and waterproofing can be taken, such as installing protective covers and using seals.

4. Regular lubrication and maintenance: The lubrication of bearings is the key to maintaining their normal working state. Select the appropriate lubricant and lubrication method according to the type of deep groove ball bearing and the operating environment, and replace the lubricant regularly to ensure that the bearings are adequately lubricated. In addition, regularly check the working conditions of the bearings, such as temperature and noise, and promptly detect and handle abnormal situations.

5. Avoid overloading and impact: During the use of the equipment, avoid subjecting the deep groove ball bearings to excessive loads and impacts. The load and impact on the bearings can be reduced by optimizing the equipment structure, improving the transmission method, and adjusting the working parameters.

6. Regular inspection and replacement: As vulnerable parts of the equipment, deep groove ball bearings should be inspected and replaced regularly. Through regular inspections, problems such as bearing wear and clearance changes can be promptly detected, and corresponding measures can be taken to address them. When the bearing is worn to a certain extent, a new bearing should be replaced in a timely manner to ensure the normal operation of the equipment.

Preventing bearing clearance change failure needs to start from multiple aspects, including selecting appropriate bearings, correct installation and disassembly, keeping clean and dry, regular lubrication and maintenance, avoiding overloading and impact, and regular inspection and replacement. Only by comprehensively considering these factors can the occurrence of bearing clearance change failure be effectively prevented.
