1. The bearing of organic fertilizer equipment is seriously worn, or the cage is damaged. Severe cases can cause heat, vibration intensification, bearing burn, and even shaft fracture.

2, the bearing quality is poor, the original clearance is small. If the bearing clearance does not meet the specification requirements, the clearance will be too small after installation, resulting in the bearing heating during operation and the temperature gradually rising.

3, bearing axial positioning error Bearing axial positioning problems, labyrinth ring or bearing gland is not installed, in the operation of the eccentric axial side movement, so that the bearing clearance is reduced, causing the bearing heat.

4, the processing error of the movable jaw bearing hole on the frame is large. Will cause the installation of two sets of bearing bush after the outer ring coaxial error, bearing load uneven, bearing heat.

5, oil hole blockage, bearing oil cut-off, too little fuel or too much oil injection, can cause the bearing temperature rise, produce abnormal phenomenon.

6, the processing accuracy of the workpiece does not meet the requirements, and the processing accuracy of the workpiece of the organic fertilizer production line equipment does not meet the requirements is also an important reason for this problem.

7. When selecting an inappropriate lubricant, the viscosity is too low and it is difficult to form an oil film, which will make the heat generated during the operation of the bearing unable to be taken away, causing the bearing to heat up.

8, non-bearing heating type sealing sleeve and end cap friction heating, or rack bearing seat double cap friction heating, can be regarded as bearing temperature rise abnormal.
