1. Inner ring and outer ring: The inner and outer ring raceways and rolling elements form an organic rotating unit.
2. Rolling body: Transfer the load between the inner and outer rings.
3. Cage: Optimizing the load keeps the rolling elements in the correct position and spacing, while preventing the rolling elements from falling off during installation.
4. Integral seal: Extend the life of the bearing, keep the lubricant in the bearing, and effectively isolate the pollutants.
