Failure modes and preventive measures of deep groove ball bearings

1. Failure Mode
Fatigue failure:
Fatigue failure is one of the common failure modes of deep groove ball bearings. When the bearing is subjected to periodic loads for a long time, its internal material will be subjected to repeated stress, which will eventually cause material fatigue and cracks. These cracks will gradually expand on the upper surface of the bearing ball or ballway until the bearing fails completely. The preventive measures for fatigue failure include reasonable design of the load distribution of the bearing, selection of high-strength materials, and optimization of the bearing structure.
Wear failure:
Wear failure is the phenomenon that the bearing surface gradually wears and the performance deteriorates due to the friction during the operation of the bearing. There are many forms of wear failure, including surface wear, fatigue wear, adhesive wear, etc. In order to reduce the occurrence of wear failure, it is necessary to ensure that the lubrication conditions of the bearing are good, use appropriate lubricants, check the wear of the bearing regularly, and replace the parts with severe wear in time.
Corrosion failure:
Corrosion failure is the phenomenon that the material performance deteriorates due to the chemical reaction between the bearing surface and the medium in the surrounding environment. The forms of corrosion failure include chemical corrosion, electrochemical corrosion, etc. In order to prevent corrosion failure, the protection of bearings should be strengthened to ensure that the bearings are in a dry and clean environment and avoid contact with corrosive media. At the same time, choosing materials with corrosion resistance to manufacture bearings is also an effective measure to reduce corrosion failure.
Overload failure:
Overload failure is caused by the load on the bearing exceeding its bearing capacity, resulting in damage or deformation of the bearing structure. Overload failure usually occurs when the bearing is subjected to impact load or heavy load. In order to prevent overload failure, the bearing capacity and structure should be reasonably designed to avoid overloading. At the same time, strengthen the monitoring and inspection of bearings, promptly detect and deal with abnormal conditions, and ensure that the bearings operate within a safe working range.
Non-natural spalling:
Non-natural spalling is a bearing failure mode caused by improper bearing selection, improper installation or improper maintenance. This failure mode usually occurs in the middle or early stage of bearing use, which has a serious impact on the performance and life of the bearing. In order to prevent the occurrence of non-natural spalling, the model and specification of the bearing should be reasonably selected to ensure the matching of the bearing and the host. At the same time, strengthen the control of the installation and commissioning process of the bearing to ensure the correct installation and stable operation of the bearing. In addition, regular maintenance and inspection of bearings, timely detection and handling of abnormal conditions are also important measures to prevent non-natural peeling.

2. Preventive measures
Reasonable selection and configuration:
Reasonable selection and configuration are one of the key measures to prevent deep groove ball bearing failure. When selecting bearings, the bearing's load capacity, speed, life and other factors should be comprehensively considered according to the use conditions and working requirements to select suitable bearing models and specifications. At the same time, attention should also be paid to the matching of the bearing and the host to ensure that the bearing can work normally and perform at its best. When configuring bearings, the installation position and number of bearings should be reasonably designed according to the structure and characteristics of the host to ensure that the bearing can evenly bear the load and reduce wear.
Correct installation and commissioning:
Correct installation and commissioning are important steps to ensure the normal operation of deep groove ball bearings. When installing bearings, the installation guide and operating procedures should be followed to ensure that the installation position and fixing method of the bearings are correct. At the same time, during the commissioning process, the load and speed should be gradually increased, the operation of the bearing should be observed, and the bearing should be able to start smoothly and operate normally. If any abnormality is found during the commissioning process, the machine should be stopped for inspection and treatment in time.
Regular maintenance and inspection: Regular maintenance and inspection are one of the important measures to prevent deep groove ball bearing failure. During the use of bearings, the bearings should be regularly lubricated, cleaned, tightened and other maintenance work to ensure that the bearings are in good working condition. At the same time, the bearings should also be inspected regularly, including appearance inspection, dimension measurement, performance testing, etc., to promptly detect and deal with abnormal conditions. For problems found, timely measures should be taken to repair or replace them to avoid the problem from expanding. Use high-quality lubricants: Using high-quality lubricants is one of the key measures to ensure the normal operation of deep groove ball bearings. Lubricants can reduce friction and wear inside bearings, reduce bearing temperature rise and noise, and improve bearing life and performance. Therefore, when selecting lubricants, the appropriate lubricant type and brand should be selected according to the type of bearing, working conditions and use requirements. At the same time, the lubricant should be replaced regularly to ensure that the cleanliness and performance of the lubricant meet the requirements. Prevent impurity intrusion: Preventing impurity intrusion is one of the important measures to ensure the normal operation of deep groove ball bearings. Impurity intrusion can cause wear and corrosion inside the bearing, reducing the performance and life of the bearing. Therefore, the sealing measures for the bearings should be strengthened to ensure the isolation of the inside of the bearings from the external environment. At the same time, the bearings should be cleaned and inspected regularly to remove impurities and dirt inside the bearings in time.
Controlling the working temperature and humidity:
Controlling the working temperature and humidity is one of the important measures to prevent the failure of deep groove ball bearings. Too high or too low temperature and humidity changes will affect the performance and life of the bearings. Therefore, measures should be taken to control the temperature and humidity of the environment in which the bearings are located to ensure that the bearings operate under suitable working conditions. For example, in a high temperature environment, cooling measures such as increasing ventilation and using cooling water can be taken; in a humid environment, moisture-proof measures such as installing a dehumidifier and using a desiccant can be taken.
