Reasons for damage to double ball bearing fan

The main reasons for damage to fan bearings include improper installation, lubrication issues, pollution, fatigue, and design defects. ‌
Improper installation: The double ball bearing fan use brute force during installation, such as hitting the bearing directly with a hammer, which can cause deformation and damage to the bearing. In addition, improper installation or failure to install in the bearing position can cause the bearing clearance to be too small, and the inner and outer rings are not in the same rotation center, resulting in non concentricity. ‌
Lubrication issue: Insufficient lubrication or poor quality of lubricating oil can cause double ball bearing fan use burns and plastic deformation. Improper viscosity of lubricating oil can also affect the normal operation of bearings, leading to increased temperature and wear. ‌

Pollution: Dust, metal shavings and other pollutants entering the double ball bearing fan use can cause damage to the bearings. This is usually caused by premature opening of bearing packaging, unclean working environment, or contamination of working media.

Fatigue: Long term overload operation, failure or improper maintenance, equipment aging, etc. of double ball bearing fan use can all lead to bearing fatigue damage. Fatigue failure is a common damage mode of bearings, manifested as metal peeling off from the raceway surface, reducing the operating accuracy of the shaft, causing vibration and noise.
Design flaw: Insufficient understanding of the actual on-site environment during the design of the double ball bearing fan, resulting in excessive equipment operating load, improper material selection, or design parameters that do not match the actual operating parameters, all of which can reduce the operating life of the equipment and increase the failure rate. ‌

Preventive and maintenance measures: Choose appropriate lubricating oil to ensure its cleanliness and viscosity are appropriate; Use professional bearing installation tools to avoid using brute force; Regular inspection and maintenance of bearings, timely cleaning of pollutants; Avoid long-term overload operation of equipment, regularly inspect and maintain equipment.
