The reason for the heating of stainless steel bearings.
 
The reasons why the stainless steel bearing exceeds the normal temperature during operation may be:
 
1. The stainless steel bearing and the journal are not uniformly fitted or the contact surface is too small (the fitting clearance is too small), and the specific pressure per unit area is too large. Most of this happens after the new machine is commissioned or replaced with a new bearing;
 
2. The stainless steel bearing is skewed or the crankshaft is bent or twisted;
 
3. The quality of the bearing bush is not good, the quality of the lubricating oil does not match (low viscosity), or the oil circuit is blocked. The oil supply pressure of the gear oil pump is too low, and the oil supply is interrupted, resulting in a lack of oil in the bearing bush, resulting in dry friction;
 
4. The stainless steel bearing has sundries or too much lubricating oil and is too dirty;
 
5. The bearing bush has uneven excessive wear;
 
6. When the compressor is installed, the shaft coupling of the main shaft and the motor (or diesel engine) is not aligned, and the error is too large, causing the two shafts to be inclined.
