2. Universal joint structure

Advantages: Allows flexible rotation in multiple directions to meet transmission requirements at different angles.
3. Inner and outer ring structure

Features: Consists of an inner ring and an outer ring, the inner ring is fixed on the rotating shaft, and the outer ring is fixed on the fixed component.
Advantages: Provides stable rotation support and load transfer.
4. Ball or needle roller assembly

Features: Use balls or needle rollers as moving elements to reduce friction and improve transmission efficiency.
Advantages: Extend service life and reduce maintenance requirements.
3. Daily maintenance
1. Regular lubrication

Method: Use appropriate grease or lubricant to lubricate the bearing regularly.
Frequency: Check the status regularly according to the use environment and load conditions, and replenish or replace if necessary.
2. Cleaning and inspection

Method: Clean the bearing surface regularly to remove dust and impurities. Check whether the bearing is worn, cracked or loose.
Frequency: Conduct a comprehensive inspection every quarter or half a year to detect and deal with problems in a timely manner.
3. Installation and removal

Method: During installation and removal, use special tools to avoid directly hitting the bearing. Ensure the matching accuracy of the bearing, shaft and seat hole.
Note: Avoid damage to the bearing during installation and ensure installation accuracy.
4. Environmental control

Method: Ensure that the working environment of the bearing is clean and avoid the intrusion of moisture and corrosive media.
Note: In high humidity and corrosive environments, additional protective measures should be taken, such as using anti-rust grease.
Conclusion
Universal hollow bearings are key components in modern mechanical equipment. They are widely used, have unique structures, and require regular maintenance to ensure their performance and life. By understanding their application areas, structural characteristics and maintenance methods, users can better use and maintain this important mechanical component to ensure the stable operation of the equipment and extend its service life.
