There may be multiple reasons for the failure of micro bearings, and the following are some common reasons:
1. Excessive load: Micro bearings are usually designed to withstand smaller loads. If the load exceeds the rated load capacity of the bearing, it can cause excessive stress and wear, leading to bearing failure.
2. Wear and fatigue: During long-term operation, the surface of micro bearings may experience wear and fatigue, leading to increased friction and material peeling.
3. Poor lubrication: The normal operation of micro bearings requires good lubrication. If there is insufficient lubrication or poor lubricant quality, it can lead to increased friction and overheating of the bearings, leading to failure.
4. Package damage: Micro bearings usually have sealing devices to prevent the entry of impurities and lubricant leakage. If the sealing device is damaged, aged, or improperly installed, it can cause external impurities to enter the bearing or lubricant leakage, accelerating bearing failure.
5. Poor installation and alignment: Incorrect installation or alignment may cause the shaft to bear additional stress and uneven loads, leading to bearing damage and failure.
6. Working environment: Adverse working environments such as high temperature, high humidity, corrosive media, etc. can cause damage to micro bearings and reduce their lifespan.
7. Material and manufacturing quality issues: Low quality bearing materials or poor manufacturing processes may lead to insufficient strength and toughness of bearings, which are prone to fracture and failure.
In order to reduce the failure of micro bearings, attention should be paid to reasonable design and selection of appropriate bearings to ensure correct installation and maintenance. Reasonably select the load and usage conditions, and conduct regular inspections and lubrication. In addition, understanding and following the manufacturer's usage guidelines and recommendations is also crucial.
