Advantages:
1. Low frictional resistance, low power consumption, high mechanical efficiency, and easy starting;
2. Size standardization, interchangeability, easy installation and disassembly, and convenient maintenance;
3. Compact structure, light weight, and smaller axial dimensions;
4. High precision, high load, low wear, and long service life;
5. Some bearings have automatic centering performance;
6. Suitable for large-scale production, with stable and reliable quality and high production efficiency;
7. The transmission friction torque is much lower than that of hydrodynamic bearings, resulting in lower friction temperature rise and power consumption;
8. The starting friction torque is only slightly higher than the rotational friction torque;
9. The sensitivity of bearing deformation to load changes is less than that of hydrodynamic bearings;
10. Only a small amount of lubricant is needed to operate normally, and lubricant can be provided for a long time during operation;
11. The axial size is smaller than that of traditional hydrodynamic bearings;
12. Can withstand both radial and thrust combined loads simultaneously;
13. Unique designs can achieve excellent performance over a large load speed range;
14. The performance of bearings is relatively insensitive to fluctuations in load, speed, and operating speed.
shortcoming
1. The noise is loud.
2. The structure of the bearing seat is relatively complex.
3. The cost is relatively high.
4. Even if the bearings are well lubricated, installed correctly, dust-proof and moisture-proof tightly, and operate normally, they will eventually fail due to fatigue on the rolling contact surface.
