FAQ
Why bearing overheating?
Bearing corrosion
There are relatively few failures of bearing corrosion when the motor is running. Generally, it is caused by the improper tightening of the bearing end cover bolts, which causes the motor to enter water during operation and the lubricant fails. If the motor does not run for a long time, the bearing will rust due to the continuous erosion of moisture.
Loose cage
Loose cage can easily cause collision and wear between cage and rolling elements during operation. In severe cases, cage rivets will be broken, lubrication conditions will deteriorate, and bearings will lock up.
The defects in the material, product accuracy, and assembly accuracy of the new bearing cage are the main reasons for the cage failure.
Fatigue peeling of bearing rolling elements
There are many reasons for the fatigue peeling of the rolling elements of the bearing. Defects in the inner and outer ring raceways of the bearing, excessive bearing clearance, overdue use of the bearing, and defects in the material of the bearing can all cause the rolling elements to peel.
The large load and high speed state of the bearing during long-term use is also one of the important reasons for bearing fatigue. The rolling elements continue to rotate and slide in the inner and outer ring raceways of the bearing. The defects of the raceway itself make the surface of the raceway uneven. The excessive clearance makes the rolling elements bear high-frequency and high-strength impact loads in motion. The material defects of the bearing itself and the use of the bearing beyond the time limit will cause the fatigue peeling of the bearing rolling elements.
