Compared to the previous two generations, the third-generation automotive wheel hub bearings have more convenience and efficiency in design and installation, such as being completely connected by bolts without the need for pressing operations, making installation more convenient. However, the usage precautions still need to be strictly followed to ensure the normal operation of the bearings and extend their service life. The following are the precautions for using third-generation automotive wheel hub bearings:
1、 Preparation before installation
Check bearings and accessories: Before installation, carefully inspect the model, specifications, appearance, and matching bolts, gaskets, and other accessories of the bearings to ensure that there are no defects such as damage, cracks, or rust.
Preparation of work environment: Ensure that the installation workplace is clean and dry, and avoid dust, impurities, etc. from entering the interior of the bearing.
2、 Installation process
Adhere to installation principles: During the installation process, strictly follow the installation instructions provided by the manufacturer to ensure that the installation steps are correct and error free. Especially, it is important to note that pressure should not be directly transmitted to the steel ball, in order to prevent the formation of pressure marks and early failure of the bearing.
Proper use of tools: Use appropriate tools for installation and avoid using hammers or other tools to strike the bearings, in order to avoid damaging the bearing structure or affecting its performance.
Check installation accuracy: Ensure the accuracy of the fit between the bearing and the shaft or hole, avoid installation deviation or looseness, which may affect the normal operation of the bearing.
Bolt tightening: For third-generation automotive wheel hub bearings, they are completely connected by bolts, so it is necessary to ensure that the bolt tightening torque is appropriate, neither too tight nor too loose, so as not to affect the sealing and stability of the bearing.
3、 Precautions during use
Regular inspection: Regularly check the operating status of bearings, including observing for any abnormal noise, high temperature, or other adverse phenomena. Once abnormalities are detected, the machine should be shut down promptly for inspection and problem-solving.
Lubrication and maintenance: Maintain sufficient lubrication of the bearing parts and follow the lubrication recommendations provided by the manufacturer. Regularly replace lubricating oil or grease to ensure that the bearings are in good lubrication condition.
Avoid overload: During use, it is advisable to avoid exceeding the rated load of the bearing to prevent damage or shorten its service life.
Pay attention to driving habits: avoid bad driving habits such as sudden braking and acceleration to reduce impact and damage to bearings.
4、 Maintenance and upkeep
Cleaning and Inspection: Regularly clean and inspect bearings to remove surface oil and impurities, and check for wear, cracks, and other damages.
Replacement and repair: Once bearing damage is found, it should be replaced or repaired in a timely manner to ensure driving safety.
Record and Summary: After each inspection, maintenance, or repair, record keeping should be done to summarize lessons learned and provide reference for subsequent maintenance.
In summary, the precautions for using third-generation automotive wheel hub bearings cover multiple aspects such as preparation before installation, installation process, precautions during use, and maintenance and upkeep. Strictly following these precautions is of great significance for ensuring the normal operation and extending the service life of bearings.
