How to maintain bearings?
The core content of bearing maintenance includes maintaining cleanliness, proper lubrication, regular inspection and maintenance. The maintenance of bearings is crucial for
extending their service life and improving work efficiency.
Firstly, maintaining cleanliness is the foundation of bearing maintenance. Dust and impurities may accumulate inside the bearing, exacerbating friction and potentially scrat
ching the bearing surface. Therefore, it is necessary to regularly clean the bearings by wiping with a soft cloth or blowing with air pressure to remove surface dust, followed
by deep cleaning with a specialized cleaner.
Secondly, proper lubrication is crucial for the smooth operation of bearings. Adequate lubrication can reduce friction and extend bearing life. Suitable lubricants should be
selected according to the type of bearing and working environment, and lubricants should be replaced regularly to avoid using too much or too little lubricant, which may
cause overheating or insufficient lubrication of the bearing.
Finally, regular inspection and maintenance are key to preventing malfunctions. Regular inspections of bearings should be conducted, including visual checks, lubrication
checks, and fixing checks, to promptly identify and address potential issues. For bearing components that are prone to wear, such as balls or retainers, they should be
replaced regularly.
In addition, there are some specific maintenance steps and methods:
Cleaning: Disassemble the bearing and clean it with a cleaning agent such as gasoline or kerosene to avoid damaging the rolling surface of the bearing.
Maintenance: Check the condition of the raceway surface, rolling surface, and mating surface of the bearing, the wear of the cage, and the damage caused by the increase in
bearing clearance and the decrease in dimensional accuracy.
Temperature control: Regularly check the bearing temperature to ensure it is within the normal range and avoid overheating.
Correct installation: Select the correct installation method and tools according to the bearing type and equipment requirements to ensure the correct alignment and fit of the
inner and outer rings of the bearing.
Avoid overloading: Ensure that the equipment operates within the rated load range and avoid overloading.
Reduce impact and vibration: Avoid exposing bearings to impact or vibration to reduce the risk of damage.
Through the above maintenance measures, the service life of bearings can be effectively extended and their working efficiency can be improved.
