The advantages of sliding bearing:

1. The coefficient of friction is large and the power consumption is much.

2. It is not suitable for mass production. The interchangeability is not good, and it is not easy to install, dismantle and repair.

3. The internal clearance is large and the processing precision is not high.  

4. The transmission efficiency is low, the heating value is large, the lubrication and maintenance are not convenient, and the lubricant is consumed.

5. The range of load, rotation speed and working temperature is narrow, the change of working condition is small, and the performance of bearing is greatly affected.

6. The radial and axial loads cannot be borne at the same time.

The advantages of sliding bearing:

1. The load capacity of the same volume as the rolling bearing is much larger.

2. The vibration and noise are small, and it is used in the case where the precision is high and the vibration is not allowed.  

3, The effect on the metal foreign matters is small, and the early-up damage is not easy to occur.
