Avoid overloading and impact: Ensure that the equipment operates within the rated load range and avoid overloading. For heavy-duty applications, choose bearings with appropriate strength and thickness. Avoid exposing bearings to impact or vibration to prevent damage or loosening.
The maintenance of bearings mainly includes the following aspects:
Cleaning: It is very important to keep the bearings and their surrounding environment clean. Avoid contact between bearings and impurities such as dust, debris, and metal particles, which may
cause bearing wear and damage. Regularly clean the area around the bearings to ensure there are no residues or debris.
Lubrication: Choosing the appropriate lubricant is crucial for the maintenance of bearings. According to the type of bearing and working environment, grease lubrication or oil lubrication can be
selected. Lipid lubrication is suitable for low-speed heavy loads, while oil lubrication is suitable for high-speed light loads. Regularly replace lubricants and avoid using too much or too little
lubricant to prevent bearing overheating or insufficient lubrication.
Temperature control: Overheating of bearings may be caused by insufficient lubrication, excessive load, or incorrect installation. Regularly check the temperature of the bearings to ensure that
they are within the normal range. For high-temperature environments or heavy-duty applications, consider using special materials and installation methods to reduce temperature.
Regular inspection and maintenance: Regularly inspect bearings, including appearance, lubrication, and fixation. For bearing components that are prone to wear, such as balls or retainers, they
should be replaced regularly. During the maintenance process, follow the correct installation method and use the correct tools to avoid further damage to the bearings.
Avoid overloading and impact: Ensure that the equipment operates within the rated load range and avoid overloading. For heavy-duty applications, choose bearings with appropriate strength
and thickness. Avoid exposing bearings to impact or vibration to prevent damage or loosening.
Installation and maintenance methods for bearings:
Cleaning: When disassembling bearings, record the appearance and confirm the remaining amount of lubricant. Use appropriate cleaning agents to clean the bearings and avoid damaging the
rolling surfaces of the bearings.
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.
Lubrication methods: including oil bath lubrication, oil dripping lubrication, circulating oil lubrication, spray lubrication and spray lubrication. Select the appropriate lubrication method according
to the rotational speed and working environment of the bearing.
Through the above maintenance and upkeep measures, the service life of bearings can be effectively extended and the performance of equipment can be improved.

Uniform force: During installation, avoid hitting only one side or using excessive force. Instead, apply even force to prevent tilting or cracking of the bearings.

The difference between tapered roller bearings and cylindrical roller bearings
Conical roller bearings: They can withstand both radial and axial loads, especially when subjected to larger radial loads, and their performance is superior to other thrust bearings. It can transmit unidirectional axial loads. If it is necessary to transmit axial loads in the opposite direction, another tapered roller bearing symmetrically installed with it is required.
