Deep groove ball bearings, as a common rolling bearing, have the characteristics of simple structure, mature manufacturing process, long service life, high precision and stability, and are widely used in various industries. When using deep groove ball bearings, the following points should be noted:

1. Lubrication: Choose the appropriate lubrication method and lubricant. Lubrication is crucial for the service life of bearings, and selecting appropriate lubrication methods and lubricants can ensure that the operating temperature of bearings is within a reasonable range.

2. Load specifications: The bearing capacity of deep groove ball bearings depends on the type and size of the bearing. When designing and selecting, factors such as load size, speed, temperature, and surface roughness should be considered to ensure that the bearing capacity is within a safe range.

3. Temperature: The working temperature of deep groove ball bearings should not be too high or too low. The working quality and stability of deep groove ball bearings will be affected in high and low temperature environments, so it is necessary to pay attention to the working temperature when using them.

4. Clean working environment: The working environment of deep groove ball bearings should be kept clean to prevent dirt from entering the interior of the bearings and affecting their service life.

5. Installation accuracy: The installation of deep groove ball bearings needs to be precise and error free to ensure the working quality and stability of the bearings. Be careful during installation and disassembly to avoid damaging the bearings.

6. Vibration and Impact: Deep groove ball bearings need to withstand certain vibrations and impacts, so it is important to avoid excessive vibration and impact during use to prevent bearing damage.

7. Environment: The usage environment of deep groove ball bearings needs to maintain appropriate humidity and temperature to avoid excessively humid or dry environments that may affect the service life of the bearings.

In summary, when using deep groove ball bearings, attention should be paid to factors such as lubrication, load specifications, temperature, clean working environment, installation accuracy, vibration and impact, and environment to ensure the working quality and stability of the bearings.
