In order to effectively avoid the failure of miniature bearings, the following measures can be taken:

1. Choose the right application: When choosing miniature bearings, you need to consider their use conditions, including speed, load, ambient temperature and humidity. Choosing miniature bearings for the right application can improve their service life and reliability.

2. Control lubrication: Miniature bearings require proper lubrication to reduce friction and wear. Choose the right lubricant and control its amount and viscosity to avoid insufficient or excessive lubrication.

3. Prevent contaminants from entering: Miniature bearings are very susceptible to contamination by tiny particles and foreign matter, which can cause increased friction and wear. Therefore, measures need to be taken to prevent contaminants from entering the bearing working environment, such as sealing the bearings or using filters.

4. Control installation and removal: When installing and removing miniature bearings, you need to use the correct tools and techniques to avoid damage to the bearings. At the same time, you need to install and adjust according to the manufacturer's recommendations to ensure the normal operation of the bearings.

5. Regular maintenance and inspection: Regular maintenance and inspection of miniature bearings, including checking lubrication conditions, cleaning or changing lubricants, checking for damage or wear, etc., can detect and solve problems in time to avoid bearing failure.

6. Choose high-quality bearings: Choosing high-quality miniature bearings can improve their material quality and manufacturing accuracy and reduce the risk of failure. At the same time, manufacturers with good reputation and word of mouth should be selected.

7. Pay attention to the use environment: The use environment of miniature bearings will also affect their life. For example, excessive temperature, humidity or corrosive environment may shorten the service life of bearings. Therefore, it is necessary to take corresponding measures according to the characteristics of the working environment, such as strengthening heat dissipation, moisture-proofing, and anti-corrosion.

8. Reasonable design of bearing seat: The unreasonable design of bearing seat will lead to uneven load distribution, local overload or uneven force of miniature bearings, which will cause bearing failure. Therefore, when designing the bearing seat, it is necessary to fully consider the characteristics and use requirements of miniature bearings to ensure that their load distribution is reasonable and the support is stable.

9. Regular replacement: Miniature bearings have a certain service life and need to be replaced after expiration. Therefore, according to the use of bearings and the recommendations of manufacturers, formulating a reasonable replacement plan and executing it on time will help avoid bearing failure.

To avoid the failure of miniature bearings, it is necessary to comprehensively consider multiple factors, take corresponding measures and carry out reasonable maintenance and management. At the same time, it is necessary to select high-quality miniature bearings and pay attention to the characteristics of the use environment and working conditions.
