Application and maintenance of deep groove ball bearings in automobiles

Deep Groove Ball Bearings

Deep groove ball bearings are the basis of automobile transmission components and are part of the driving device on the automobile. Although the automobile bearing is not very eye-catching, it has an important relationship with the safety, reliability and comfort of the vehicle, and is known as the "joint of the automobile industry". Since automobile bearings are so important, let me introduce some methods of using and maintaining automobile bearings.

  1. Prohibit automobile bearings from being subjected to abnormal loads acting on components at a high speed, which may easily cause deformation of automobile bearings.

  2. Automobiles and vehicles need to work within the rated load range. If it is seriously overloaded, it may cause the bearing to be overloaded, causing the bearing to fail in the early stage of use. The more serious consequence is that the pit will cause vehicle failure or safety accidents.

  3. Fill the bearing with grease or lubricating oil regularly and quantitatively as required.

  4. According to the number of times the vehicle is used, completely replace it with new lubricating oil at least every six months.

  5. Regularly check the use status of the bearings, and pay attention to observe whether there are abnormal noises in the bearing parts or excessive local heating.

  6. The inspection method of the bearing in the maintenance state is: use kerosene or gasoline to clean the disassembled automobile bearing, observe whether there is sliding or creeping on the inner and outer cylindrical surfaces of the automobile bearing, and whether there is peeling or pitting on the inner and outer rolling surfaces of the bearing The condition of the rolling element and the cage are worn and deformed, etc.
