Attention to Maintenance of Automobile Hub Bearing

Properly lubricate and extend bearing life. It is also important to use proper pure oil or lubricating oil to maintain bearing lubrication. Different lubrication methods shall be adopted according to speed and load. The lubricating properties include brightness, oil film forming ability and lubricating consistency. The selection criteria of lubricating oil include the scope of equipment, speed, environment and other working conditions. Bearings used at normal speeds and temperatures should normally be used for lubrication. For higher speed or bearing requiring heat dissipation, the circulating system shall be used to continuously supply essential oil. The lubricant has good adhesion and can prevent pollution and moisture

The interval between changing oil and lubricating oil depends on the operating temperature and other environmental factors. Contaminants such as water or chemicals can corrode bearing surfaces or damage lubricating oil. The seal can effectively prevent pollutants from entering the bearing and prolong the service life of the bearing. Friction contact and non friction clearance or sealing labyrinth are two main forms. If a certain sealing effect is very small, the combination of these two forms will usually improve the sealing quality. Cleaning is the key for bearings. The bearing must work without contamination. Dust, cutting dust and other solid particles, abrasive particles and soft particles such as fiber chips, dandruff and plastic are
